difference between male gametophyte and female gametophyte

Male gametophyte leaves the microsporangium while female gametophyte remains inside the megasporangium. What is the Difference Between Male and Female Gametophyte      – Comparison of Key Differences, Female Gametophyte, Male Gametophyte, Megaspore, Microspore, Ovule, Pollen Grain. The main difference between male and female gametophyte is their structure and function. Female gametophyte is the haploid stage that produces female gametes. We can say the growth phase also as another difference between male and female gametophyte. 35. Degree in Plant Science, M.Sc. Male gametophyte refers to the life stage of heterosporous plants which produces male gametes while female gametophyte refers to the life stage of heterosporous plants which produces female gametes. Male gametophyte produces male gametes while female gametophyte produces female gametes. The main difference between gamete and gametophyte is that gamete is a mature haploid male or female germ cell, which is able to unite with another of the opposite sex in sexual reproduction to form a zygote, whereas gametophyte is the haploid phase of the life cycle of a plant, producing gametes. It does not remain permanently embedded inside the microsporangium. “Male Gametophyte Male Gametophyte Pinus Staminate Zoomed” By Iceclanl – Own work (CC BY-SA 3.0) via Commons Wikimedia 30. The spore develops into a gametophyte which is haploid in nature. Figure \(\PageIndex{1}\): Male and female gametophytes: These series of micrographs shows male and female gymnosperm gametophytes. As in Cycas. “Angiosperm embryo sac diagram” By BlueRidgeKitties (CC BY 2.0) via Flickr, Lakna, a graduate in Molecular Biology & Biochemistry, is a Molecular Biologist and has a broad and keen interest in the discovery of nature related things, What is the Difference Between Male and Female Gametophyte, What are the Similarities Between Male and Female Gametophyte. Microspores produce the male gametophyte while macrospores produce the female gametophyte. Male gametophyte refers to the male gamete bearing part of the body of the organism or the part of the body that contains the ultimate gamete of male i.e. When two gametes fuse with each other, a diploid cell known as zygote forms and continues into sporophytic generation. During the evolution of plant life, a variation can be seen in the development of the reproductive system of a plant depend… Michael Borg, Lynette Brownfield, David Twell; Male gametophyte development: a molecular perspective, Journal of Experimental Botany, Volume 60, Issue 5, 1 April 2009, Pages 1465–1478, Available Here2. The main difference between male and female gametophyte is that the microspore or pollen grain produces the male gametophyte while the megaspore produces the female gametophyte. in Molecular and Applied Microbiology, and PhD in Applied Microbiology. Male gametophyte is the haploid stage that produces male gametes. It is derived from a pollen grain or micro­spore. Moreover, upon germination, the generative cell nucleus produces two germ nuclei, which serve as the male gametes. The male gametophyte has two phases of growth while the female gametophyte has a single phase of growth. The gametophyte … Female gametophyte is the female gamete-producing structure, which comes from the megaspore. 36. The gametophyte consisting of reproductive organs undergo mitosis to form haploid gametes. Both algae and plants show these structures, which give rise to the phenomenon of alternation of generations. The pollen grain germinates on the stigma, producing the pollen tube, which burrows into the ovary through the style. Dr.Samanthi Udayangani holds a B.Sc. Similarities Between Male and Female Gametophyte 6. Following are the differences between both stages: The gametophyte is the haploid(n) state in the life cycle whereas sporophyte is the diploid(2n) state in the life cycle. Thus, both produce gametes that will undergo fertilization to produce new organisms in the mode of sexual reproduction. So, we can consider this too as a difference between male and female gametophyte. The difference between Gametophytes and Sporophytes is the type of phase they play in a plant’s life. One cell develops into the megaspore, which can give rise to the gametophyte. The difference between the male gametophyte of pteridophytes and gymnosperms are:Male gametophyte of Pteridophyte Male gametophyte of gymnosperms Distinct male gametophyte may not be present Distinct male gametophyte is always present. The female gametophyte is the structure that produces female gamete cells in algae and plants. In plants, alternation of generations exists, where the members have haploid and diploid phases. Main Difference – Gametophyte vs Sporophyte Gametophyte and sporophyte are the sexual and asexual phases that occur during the alteration of generations of plants. In angiosperms, microspore contains a single haploid nucleus, which undergoes mitosis to produce two nuclei: tube nucleus and generative cell nucleus. 4. Only pre-pollination growth occurs … ADVERTISEMENTS: Some of the major differences between male and female gametophytes flowering plant are as follows: Male Gametophyte: 1. In gymnosperms where the main reproductive structure is the flower, the male gametophyte occurs in the pollen grains. The walls of the ovary develop into fruit. Male gametophyte is inside the pollen grain while female gametocyte is inside the ovule. The female gametophyte contains seven-celled and eight nucleate embryo sac. Heterospory mainly occurs in seed plants. They are megaspores, which germinates to produce the female gametophyte and the microspores, which germinates to produce the male gametophyte. 1. Therefore, female gametes are usually non-flagellated. Each pollen grain is reduced to two or three cells in a waxy protective coat. The microspores are produced from the microsporangia whereas the megaspores are produced from the megasporangia. They represent one of the two generations in the alteration of generations in plants. This stage of megaspore is known as the female gametophyte. Male and female gametophytes are the two gametophytic stages of heterosporous plants. In contrast, the male gametes produced from the male gametophyte of gymnosperms undergo internal fertilization inside the female gametophyte or the ovary. It has two phases of growth— pre-pollination and post-pollination. The male gametophyte derives from the microspore while the female gametophyte derives from the megaspore. The male gametophyte gives rise to male gametes while the female gametophyte gives rise to female gametes. Moreover, the female gametophyte undergoes meiosis to produce four haploid cells. 1. As in Cycas. ADVERTISEMENTS: 2. Side by Side Comparison – Male vs Female Gametophyte in Tabular Form 31. Male gametophyte has three cells while female gametophyte has eight cells. Moreover, another difference between gamete and gametophyte is that the gamete is a haploid unicellular structure while the gametophyte is a haploid multicellular structure. What is Female Gametophyte      – Definition, Structure, Role 3. “The Female Gametophyte.” The Arabidopsis Book / American Society of Plant Biologists 9 (2011): e0155. The triploid nucleus later becomes the endosperm. The male cone produces tiny amounts of pollen grains that become the male gametophyte. The key difference between male and female gametophyte depends on the derivation of each gametophyte. Cloudflare Ray ID: 5db6bdc5eac30820 2.The male gamete is conical from the front while the female gamete is spherical. A cell inside the nucellus of the ovule known as megasporocyte undergoes meiosis to produce four cells. Know the Differences between Archegonia, Antheridia, Microspore, Megaspore, Pollen Grain, Ovary, Ovule, Seed, Embryo, Male Gametophyte and Female Gametophyte. Skinner, Debra J, and Venkatesan Sundaresan. The male gametophyte inside the pollen grain represents the first stage of growth. This explains the basic difference between male and female gametophyte. 1. In other heterosporous plants, microspores are produced in the microphylls. The male gametes produced by the male gametophyte perform external fertilization in algae and requires an aquatic medium. The term gametophyte may refer to the gametophyte phase of the plant life cycle or to the particular plant body or organ that produces gametes. Gymnosperms are agroup of plants that share one common characteristic in that they bear seeds,but their seeds do not develop from within an ovary. They give rise to the sexual reproduction cycle in algae and plants. Gametophytes are known as the diploid segment of the plant cycle and the Sporophytes are the haploid part of the plant cycle. Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. The gametophyte produces male and female gametes directly from its plant body. In angiosperms, microsporangium occurs inside the anther while in gymnosperms, it occurs in the pollen cone. “Angiosperm embryo sac diagram” By BlueRidgeKitties (CC BY 2.0) via Flickr. These grains have winglike structures that allow the wind to carry them up the tree to the female cones. The megaspore develops into the female gametophyte, whereas the microspore develops into the male gametophyte. One of the haploid cells becomes the egg cell. The female gametophyte produces non- motile or less motile female gametes in both algae and plants. The male gametophyte found in plants and algae produces male reproductive cells that are usually motile and flagellated. In gymnosperms, it is produced in the female cone while in other heterosporous plants, it is produced in megaphylls. Furthermore, they produce gametes that are capable of undergoing sexual reproduction. This cycle is named alternation of generations and organisms alternate between a sexual phase, or gametophyte generation and an asexual phase, or sporophyte generation. Drews, Gary N., and Anna M.G Koltunow. Angiosperms: Just like its fellow seed bearing group member, Angiosperms have sporophyte as dominant form. 2. Female gametophyte bears one or two archegonia; no neck canal cell. 5. 4. They represent the gametophyte generation of plants and algae. The microspore gives rise to the male gametophytes while the megaspore gives rise to the female gametophyte. Male and female gametophytes are the two gametophytic stages of heterosporous plants. The male gametophyte develops reproductive organs called antheridia (produce sperm) and the female gametophyte develops archegonia (produce eggs). The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte. Plants reproduce via asexual reproduction as well as via sexual reproduction. Gamete: 1. Male and female gametophytes arise from hetero spores. The endosperm is produced before fertilization. Megasporangium produces the megaspores inside the ovary in angiosperms. Male gametophyte originates inside the microsporangium while female gametophyte originates inside the megasporangium. Separate male and female gametophytes are common which develop in micro and megaspores respectively. In gametophyte, male or female gametes are produced. Though the stages are common in different plant groups, their level of complexity and status across various groups is different. Moreover, sporophyte produces haploid spores while the gametophyte produces male and female gametes. Summary. There are two types of gametes: male and female, involved in sexual reproduction. What are the Similarities Between Male and Female Gametophyte      – Outline of Common Features 4. One of the four cells become the megaspore, which undergoes three mitotic divisions to produce eight haploid nuclei. The non-motile sperms are carried to the mouth of archegonia through pollen tube; pollen tube acts as sperms carrier and haustorium. Male gametophyte and female gametophyte represent the gametophytic generation or the haploid generation of plants and in some algae. Differences between male gametophyte and female gametophyte are given in following table:- 1) male gametophyte is derived from Pollen Grain or microspore which are formed in Pollen sac of anther whereas female gametophyte is derived from megaspore which is formed in nucellus of ovule. This is a main difference between male and female gametophyte. Spore is the first cell of the gametophyte, which germinate to produce gametophyte. Male gametophyte is inside the pollen grain while female gametophyte are inside the ovum. The key difference between male and female gametophyte depends on the derivation of each gametophyte. It derives from the microspore. Home » Science » Biology » Botany » What is the Difference Between Male and Female Gametophyte. Furthermore, all the cells in the male gametophyte are functional while only two cells in the female gametophyte are functional. References: 1. The key difference between sporophyte and gametophyte is that the sporophyte is a diploid structure that participates in asexual reproduction while the gametophyte is a haploid structure that participates in sexual reproduction of plants. What is Male Gametophyte      – Definition, Structure, Role 2. Key Differences Between … Mostly spores are surrounded by a thick wall to avoid extreme conditions.

Male and female gametophytes produce their respective male and female gametes that are necessary for sexual reproduction. The microspore or pollen grain produces the male gametophyte while the megaspore produces the female gametophyte. All rights reserved. The only difference is that the gametophyte is more intricately developed in this group when compared to the former one. Heterosporous plants produce both male and female gametophytes. So, the gametophyte is known as the sexual phase during sporophyte as the asexual phase of the plant’s life. Lastly, wind plays an important role in pollination in gymnosperms because pollen is blown by the wind to land on the female cones. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. sperm in humans, pollens in flowers etc. Web. While the female gametophyte produces female gamete or the egg cell, the male gametophyte produces male gamete or the sperm cell. These reproductive cells leave the gametophyte and undergo fertilization with the female gamete. The male and female gametophyte structures are present on separate male and female cones in gymnosperms, whereas in angiosperms, they are a part of the flower. The below infographic summarizes the difference between male and female gametophyte. 13 Sept. 2018, Available Here, 1. 4. Alternation of generations between sporophyte and gametophyte takes in the following stages: Sporangium present in diploid sporophytes undergo meiosis to form haploid spores. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } This is yet another difference between male and female gametophyte. and the structure that bears it like testes in humans and anther in flowers are male gametophytes. Both gametophyte and sporophyte are multicellular structures. Male gametes small non-motile. The key difference between male and female gametophyte depends on the type of cell which produces the two structures. The whole structure is called the young pollen grain. What is Female Gametophyte A gametophyte represents the sexual phase of the plant life. Terms of Use and Privacy Policy: Legal. Gametophyte is unisexual. PMC. The gametophyte is a haploid phase in which haploid male and female gametes are produced whereas; sporophyte is a diploid phase in which diploid spores are produced. What is Male Gametophyte 3. Female gametes are larger than male gametes. Ans. 3. As in Cycas. However, these organisms also show alternation of generations between the sporophytic and the gametophytic generation. It comes from the microspore produced by the microsporangium in heterosporous plants including angiosperms, gymnosperms, lycophytes, and horsetails. Difference Between Homosporous And Heterosporous Pteridophytes In Tabular Form Difference Between Gametophyte And Sporophyte. The female gametophyte arises from the megaspore via the formation of the megasporangium. Overview and Key Difference The main difference between male and female gametophyte is that the microspore or pollen grain produces the male gametophyte while the megaspore produces the female gametophyte. Why Sporophyte is dominant over Gametophyte? Additionally, the female gametophyte is formed inside the megasporangium in seed plants, while the male gametophyte is formed near the female gametophyte. Male and female gametophyte are the two types of gametophytes produced by heterosporous plants. The microspore gives rise to the male gametophyte via formation of the microsporangium. 32. The structure that produces the male gamete cells is the male gametophyte. Thus, both produce gametes that will undergo fertilization to produce new organisms in the mode of sexual reproduction. 3. Male gametophyte is the male gamete-producing structure. 3.Male gametophyte(a 3-celled structure)comes out of the microspore by forming a pollen tube. 1. However, the main difference between homospory and heterospory is the size and the sex of the spores produced by plants. ...

Upon maturity, the male gametophyte (pollen) is released from the male cones and is carried by the wind to land on female cones. Moreover, both are derived from their respective spores. Both are haploid and are derived from the corresponding spores. 2. 33. The male gametophyte derives from the microspore while the female gametophyte derives from the megaspore. Main difference is their structure and function. In angiosperms, the female gamete produced by the female gametophyte undergoes triple fusion. The male gametophyte is also called antheridium. Examples ofgymnosperms include pine, conifers, cycads, Gnetophytes, Ginkgo, spruce, cactusand fir. The germination phase represents the second phase of growth in the male gametophyte, consisting of three cells. As nouns the difference between gametophyte and bisexual The male gametophyte contains two tough walls called exine and intine. A male gametophyte is a haploid adult stage of a male organism that produces gametes. “Male Gametophyte Male Gametophyte Pinus Staminate Zoomed” By Iceclanl – Own work (CC BY-SA 3.0) via Commons Wikimedia 2. Antheridia: Male reproductive structure of mosses and ferns produces the sperms. Classification of plants In Psilophytes, Bryophytes and Lycophytes, the sporophyte depends on gametophyte stage whereas, in angiosperms, this stage is longer than gametophyte. Difference Between Gametophyte and Sporophyte: Conclusion In conclusion, understanding the gametophytes vs sporophytes concept is an important aspect of the biological sciences. It derives from the megaspore. Thus, microspores, link sporophytic generation and gametophytic generation during the alternation of generations. Male gametophyte disintegrates after fertilization while female gametophyte produces new structures after fertilization. In gametophyte, gametes are produced by meiosis. Female gametophyte is haploid stage that produces female gametes.It derives from megaspores. With respect to the former, experts have carried … The egg cell fuses with the male gamete to form the zygote. Angiosperms undergo triple fusion; here, one of the germ nuclei from the male gametophyte fuses with the egg nuclei, forming the zygote, and the other germ nucleus fuses with the two polar nuclei, forming a triploid nucleus. Compare the Difference Between Similar Terms. In context|botany|lang=en terms the difference between gametophyte and bisexual is that gametophyte is (botany) a plant (or the haploid phase in its life cycle) which produces gametes by mitosis in order to produce a zygote while bisexual is (botany) of fungi: producing both the "female" ascogonium and the "male" antheridium. Moreover, the germ cell nucleus fuses with the two polar nuclei to form the triploid nucleus that develops into the endosperm. Number of cells and their functionability is the next major difference between male and female gametophyte. The union of two gametes during fertilization produces a diploid … “Recent Advances in Understanding Female Gametophyte Development.” F1000Research, F1000 Research Limited, 20 June 2018, Available here. Another difference between male and female gametophyte is their origin. The key difference between male and female gametophyte is about the derivation of the gametophytes. 34. Microspore with the two nuclei stage is called the male gametophyte. It leaves the microsporangium and is captured by the stigma. 1. Antheridium is present Antheridium is absent Male gametes are flagellated Male gametes may or may not be flagellated Male gamete needs water … Read on to explore more differences between the two. Also, the origin of the male gametophyte is the microsporangium, whereas the origin of the female gametophyte is the megasporangium. Produce two types of gametophytes: male and female gametophyte.
