“Male Gametophyte Male Gametophyte Pinus Staminate Zoomed” By Iceclanl – Own work (CC BY-SA 3.0) via Commons Wikimedia Plants reproduce via asexual reproduction as well as via sexual reproduction. They represent one of the two generations in the alteration of generations in plants. The female gametophyte arises from the megaspore via the formation of the megasporangium. In gymnosperms where the main reproductive structure is the flower, the male gametophyte occurs in the pollen grains. The non-motile sperms are carried to the mouth of archegonia through pollen tube; pollen tube acts as sperms carrier and haustorium. It is derived from a pollen grain or microspore. and the structure that bears it like testes in humans and anther in flowers are male gametophytes. Thus, microspores, link sporophytic generation and gametophytic generation during the alternation of generations. One of the haploid cells becomes the egg cell. 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. References: 1. The male gametophyte derives from the microspore while the female gametophyte derives from the megaspore. We can say the growth phase also as another difference between male and female gametophyte. Upon maturity, the male gametophyte (pollen) is released from the male cones and is carried by the wind to land on female cones. A cell inside the nucellus of the ovule known as megasporocyte undergoes meiosis to produce four cells. Microspores produce the male gametophyte while macrospores produce the female gametophyte. One cell develops into the megaspore, which can give rise to the gametophyte. The male gametophyte develops reproductive organs called antheridia (produce sperm) and the female gametophyte develops archegonia (produce eggs). @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } } As in Cycas. Male gametophyte is the haploid stage that produces male gametes. 4. Overview and Key Difference (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. 34. Male gametophyte is inside the pollen grain while female gametocyte is inside the ovule. Mostly spores are surrounded by a thick wall to avoid extreme conditions. Gamete: 1. They give rise to the sexual reproduction cycle in algae and plants. Home » Science » Biology » Botany » What is the Difference Between Male and Female Gametophyte. The male gametophyte derives from the microspore while the female gametophyte derives from the megaspore. Moreover, sporophyte produces haploid spores while the gametophyte produces male and female gametes. The microspore gives rise to the male gametophytes while the megaspore gives rise to the female gametophyte. Read on to explore more differences between the two. Furthermore, all the cells in the male gametophyte are functional while only two cells in the female gametophyte are functional. 6. Megasporangium produces the megaspores inside the ovary in angiosperms. Additionally, the female gametophyte is formed inside the megasporangium in seed plants, while the male gametophyte is formed near the female gametophyte. in Molecular and Applied Microbiology, and PhD in Applied Microbiology. The female gametophyte produces non- motile or less motile female gametes in both algae and plants. Moreover, the germ cell nucleus fuses with the two polar nuclei to form the triploid nucleus that develops into the endosperm. 30. The key difference between male and female gametophyte depends on the derivation of each gametophyte. There are two types of gametes: male and female, involved in sexual reproduction. ADVERTISEMENTS: Some of the major differences between male and female gametophytes flowering plant are as follows: Male Gametophyte: 1. 2. A gametophyte represents the sexual phase of the plant life. Figure \(\PageIndex{1}\): Male and female gametophytes: These series of micrographs shows male and female gymnosperm gametophytes. Male and female gametophytes are the two gametophytic stages of heterosporous plants. This cycle is named alternation of generations and organisms alternate between a sexual phase, or gametophyte generation and an asexual phase, or sporophyte generation. Female gametophyte bears one or two archegonia; no neck canal cell. They are megaspores, which germinates to produce the female gametophyte and the microspores, which germinates to produce the male gametophyte. This is a main difference between male and female gametophyte. The whole structure is called the young pollen grain. Male gametophyte originates inside the microsporangium while female gametophyte originates inside the megasporangium. 1. As in Cycas. Alternation of generations between sporophyte and gametophyte takes in the following stages: Sporangium present in diploid sporophytes undergo meiosis to form haploid spores. “Angiosperm embryo sac diagram” By BlueRidgeKitties (CC BY 2.0) via Flickr. The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte. Both are haploid and are derived from the corresponding spores. Moreover, both are derived from their respective spores. When two gametes fuse with each other, a diploid cell known as zygote forms and continues into sporophytic generation. In other heterosporous plants, microspores are produced in the microphylls. 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. The male gametophyte gives rise to male gametes while the female gametophyte gives rise to female gametes. Only pre-pollination growth occurs … The walls of the ovary develop into fruit. Male gametophyte disintegrates after fertilization while female gametophyte produces new structures after fertilization. 3. 5. Female gametophyte is haploid stage that produces female gametes.It derives from megaspores. Male gametophyte is inside the pollen grain while female gametophyte are inside the ovum. During the evolution of plant life, a variation can be seen in the development of the reproductive system of a plant depend… Furthermore, they produce gametes that are capable of undergoing sexual reproduction. Difference Between Homosporous And Heterosporous Pteridophytes In Tabular Form 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. What is Female Gametophyte As in Cycas. The endosperm is produced before fertilization. Difference Between Gametophyte and Sporophyte: Conclusion In conclusion, understanding the gametophytes vs sporophytes concept is an important aspect of the biological sciences.
