What is female gametophyte?
Embryo sac is the female gametophyte of flowering plants. Situated in the flower. It is dependent on the sporophyte (what we call plant) for nutrition. here the gametophyte is reduced and sporophyte is dominant.In lower plants the female gametophyte is prominent and independent where it can photosynthesize. Usually it is called as a thallus. Here the sporophyte is reduced and the gametophyte is dominant.
Why do gametophytes die after the sporophyte starts to grow?
The gametophyte is responsible for producing gametes, both male and female. When a male gamete fertilizes the female gamete, a zygote, or fertilized cell is created. This zygote matures and grows (through mitosis) into a sporophyte. At this point, the gametophyte has already done its job, and is not needed. Therefore it dies. The sporophyte releases spores, which eventually develop into gametophytes, and the cycle restarts.
The life cycle of nonvascular plants includes an alternation of generations between a?
The life cycle of nonvascular plants includes an alternation of generations between a gametophyte and a sporophyte. The gametophyte generation produces gametes (eggs and sperm) through mitosis, which then fuse to form a zygote that develops into the sporophyte generation through mitosis. The sporophyte produces spores through meiosis that develop into new gametophytes.
Will megaspores divide to form the female gametophyte or the sporophyte?
It will divide to form the female gametophyte.
Inherited differences in the appearances of two brothers are due to the what that occurred during the production of gametes in their parents?
Inherited differences in appearance between siblings are due to the random assortment of genes during gamete formation in the parents. The combination of genes from each parent creates unique genetic variations in their offspring.
Do eggs have gametophyte or sporophyte?
Egg being a gamete develops inside gametophyte
What is the advantage of having a reduced gametophyte when compared to non vascular plants?
A reduced gametophyte has to waste less material for gamete formation
does the sperm cell come from male or female?
Gametes come from both the mother and the father. The mother's gamete is known as an egg and the father's gamete is known as a sperm.

What portions of the pine nut are diploid?
The embryo and endosperm of the pine nut are diploid. The embryo is formed from the fusion of a male gamete (sperm) and a female gamete (egg), both of which are haploid, resulting in a diploid zygote. The endosperm is also formed from a fusion of a male gamete and a central cell in the female gametophyte.
Contrast microspores and megaspores?
Microspore = male gamete (n)Megaspore = female gamete (n) Micro develops in the anther and undergoes mitosis to create pollenMega develops in the ovule, retained in ovary, and undergoes mitosis to create female gametophyte (ultimately, an egg).
What gamete producing haploid form of the green alga ulva is known as an?
The gamete producing haploid form of the green alga Ulva is known as a gametophyte. This stage in the Ulva life cycle produces male and female gametes that eventually fuse to form a zygote.

What is the egg cell in a female's body?
The egg cell, also called the haploid cell, is the female gamete. A pair of gametes, egg and sperm, are what are needed in order for reproduction to occur.
The green leafy moss plant is part of what moss cycle?
The green leafy moss plant is part of the gametophyte phase of the moss life cycle. Mosses alternate between a gametophyte stage (producing male and female gametes) and a sporophyte stage (producing spores).
When a plants life cycle alternates between a sporophyte and gametophyte?
photosynthesis
Gametophyte and sporophyte?
Gametophyte-haploid Sporophyte-diploid
