A gamete is a mature reproductive cell (sperm or egg) that fuses with another gamete during fertilization. A gametophyte is a haploid multicellular plant structure that produces gametes through mitosis. Gametes are reproductive cells in animals, while gametophytes are multicellular structures in plants that produce gametes.

What is female gametophyte?
Female gametophyte is a structure in plants that produces female gametes (eggs) through the process of mitosis. It is typically found within the ovule of the flower and is essential for sexual reproduction in plants. The female gametophyte is haploid, meaning it has a single set of chromosomes.
Why do gametophytes die after the sporophyte starts to grow?
Gametophytes die after the sporophyte starts to grow because their purpose is fulfilled. The gametophyte produces gametes that combine to form a new sporophyte, which will become the dominant generation in the plant life cycle. Once the sporophyte is established and able to produce its own spores, the gametophyte is no longer needed and naturally senesces and dies.
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?
Megaspores 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 is female gametophyte?
Female gametophyte is a structure in plants that produces female gametes (eggs) through the process of mitosis. It is typically found within the ovule of the flower and is essential for sexual reproduction in plants. The female gametophyte is haploid, meaning it has a single set of chromosomes.
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.
Why do gametophytes die after the sporophyte starts to grow?
Gametophytes die after the sporophyte starts to grow because their purpose is fulfilled. The gametophyte produces gametes that combine to form a new sporophyte, which will become the dominant generation in the plant life cycle. Once the sporophyte is established and able to produce its own spores, the gametophyte is no longer needed and naturally senesces and dies.
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
