In angiosperms the male gametophyte is?
The male gametophyte in an angiosperm is the stamen. The female gametophyte in an angiosperm is the pistil.This is completely wrong. The male gametophyte consists of the generative cell and the tube cell in the pollen grain. The female gametophyte is the 7-celled 8 nucleate embryo sac.
What structure directly precedes the development of both a male and female gametophyte?
The development of both a male and female gametophyte is preceded by meiosis, where a diploid sporophyte cell undergoes two rounds of division to produce haploid cells called spores. These spores then develop into the gametophytes through mitotic division.
Name the parts of an angiosperm flower in which development of male and female gametophyte take place?
Parenchyma cells Stamen & pistil
Do gametophytes produces seeds or pollen?
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
What is the male gametophyte in a cone bearing plant?
In cone-bearing plants, also known as gymnosperms, the male gametophyte is represented by pollen grains. These pollen grains develop from microspores within the male cones (strobili) and contain the male gametes (sperm cells). When pollen is transferred to a female cone, it can fertilize the ovule, leading to the formation of seeds. Thus, the male gametophyte plays a crucial role in the reproductive process of these plants.
Is stamen the mature male gametophyte?
No. The stamen is the male structure of the flower, consisting of a filament and anther. However, the mature, male gametophyte consists of a germinated pollen grain with its tube and two associated sperm.
The megaspore of a conifer will become?
The megaspore of a conifer will become the female gametophyte, which contains the egg cell. This structure is essential for fertilization and seed production in conifers.
In seed plants the structure that encloses the male gametophyte and transports it to another plant is called a?
In seed plants, the structure that encloses the male gametophyte and helps transport it to another plant is called pollen. Pollen grains contain the male gametophyte, which is the microgametophyte. When released from the anther of a flower, pollen can be carried by wind, insects, or other pollinators to reach the female reproductive structures of another plant, allowing for fertilization.
In angiosperms the male gametophyte is?
The male gametophyte in an angiosperm is the stamen. The female gametophyte in an angiosperm is the pistil.This is completely wrong. The male gametophyte consists of the generative cell and the tube cell in the pollen grain. The female gametophyte is the 7-celled 8 nucleate embryo sac.

What is one entire male gametophyte of a gymnosperm?
The male gametophyte of a gymnosperm is a pollen grain, which consists of two cells: a generative cell that will divide to form two sperm cells, and a tube cell that aids in the pollen tube formation.
Name the parts of an angiosperm flower in which development of male and female gametophyte take place?
Parenchyma cells Stamen & pistil
Does sorus have gametophyte or sporophyte?
Sorus is a structure found on the underside of fern leaves that contains the sporangia, which produce spores. The spores give rise to the gametophyte generation in ferns.
Do gametophytes produces seeds or pollen?
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
Which part of the life cycle does a pollen grain represent?
a male gametophyte
Is the gametophyte not free living in bryophytes?
In bryophytes, the gametophyte is the dominant, free-living stage of the life cycle. It is the structure responsible for producing gametes and supporting fertilization. The gametophyte in bryophytes usually grows independently from the sporophyte, which is dependent on the gametophyte for nutrition and support.
What is the function of the spore of gymnosperms?
The gymnosperms produce megaspores and microspores. A microspore is the male spore and megaspore is the large female spore. The microspore undergoes mitosis to produce the multicellular male gametophyte. These male gametophytes are the pollen grains that are contained inside short pollen cones. The megaspore is the large female spore that undergoes mitosis to produce the multicellular female gametophyte that is housed in a large female cone.
