How many meiotic and mitotic divisions are required for the development of 1 female gametophyte?

The number of meiotic and mitotic divisions necessary for development of female gametophyte in angiosperms is 1 meiosis and 3 mitosis.

How many mitotic divisions are required for development of female gametophyte?

Thus, one meiotic division produces one matured female gametophyte in an angiosperm. Hence, 101 meiotic divisions are required to produce 101 female gametophytes in an angiosperm.

How many divisions take place in the formation of female gametophyte?

Gamete Formation

From the remaining functional megaspore, the megagametophyte (also known as female gametophyte or embryo sac) develops by three mitotic divisions, at the mature stage consisting of 8 nuclei and 7 cells (one egg cell, two synergids, one central cell and three antipodals).

How many mitotic division takes place for complete development of female gametophyte in angiosperms?

This nucleus undergoes two rounds of mitosis, producing a four-nucleate coenocyte, with two nuclei at each pole separated by a large central vacuole (stage FG4).

How many meiotic and mitotic divisions are required for the formation of mature male gametophyte?

Hence, one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.

How many mitotic divisions take place for complete development of embryo sac?

During development of the corn embryo sac, which displays the so-called polygonum type of development, three mitotic divisions give rise to two groups of four nuclei, one at the end closest to the embryo (the micropylar end) and one in the opposite (chalazal) end of the embryo sac.

How many mitotic divisions are required for the formation of 100 mature embryo sac?

There are three mitotic divisions to form a mature embryo sac from megaspore mother cell.

How many mitotic divisions are required for the formation of male gametophyte?

After pollination, the generative cell after entering into the pollen tube divide mitotically to form two non-motile male gametes. Hence, one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.

How many mitotic divisions are required for the formation of male gametes?

The formation of the male gamete requires only one meiotic division which results in four male gametes while the formation of four female gametes requires four meiotic divisions.

How many mitotic and meiotic divisions are required to form a megaspore?

So, only 25 meiotic division is required for 100 megaspores. But, for 100 functional megaspores, 100 meiotic divisions are required.

How many meiotic and mitotic division are required for the formation of female gametophyte from functional megaspore?

2 meiotic and 1 mitotic.

How many meiotic and mitotic divisions takes place for the formation of a single female gametophyte from Megaspore mother cell?

The female gametophyte, also known as embryo sac, develops within the ovule [1,2]. A region called the nucellus gives rise to a single pre-meiotic cell—the megaspore mother cell (MMC). MMC undergoes two meiotic divisions resulting in four haploid megaspores.

How many meiotic and mitotic divisions are required for the formation of 100 seeds?

So, for the development of 100 megaspores 100 meiotic division is required. – So, by the fusion of 100 microspores and 100 megaspores, 100 seeds are formed. – Hence for the 100 seed production 200 meiotic division takes place in the Cyperaceae family. Hence, the correct answer is option (D).

How many mitotic and mitotic divisions are required for the formation of male gametophyte from pollen mother cell?

These processes are necessary for the complete development of male gametophyte from Pollen mother cell. One meiotic and two mitotic divisions.

How many mitotic divisions are required for the formation of?

Correct answer is 8. There are two formulas: 1. Number of mitotic divisions required for formation of n number of cells is n-1.

How many mitotic divisions are required for the formation of 100 pollen grains?

One meiotic division in a pollen mother cell gives rise to 4 microspores, which develop into 4 pollen grains, therefore 25 meiotic divisions are required to produce 100 pollen grains.
