# Question: How many mitotic divisions are required for the formation of 100 functional Megaspore?

Contents

So, only 25 meiotic division is required for 100 megaspores.

## How many mitotic divisions are needed from a functional Megaspore?

3 mitotic divisions to form mature embryo sac.

## How many meiotic divisions are required for the formation of 100?

Hence, the correct answer is 125 meiosis divisions will be done for the formation of 100 zygotes in humans.

## How many meiotic divisions are required for the formation of 100 pollen grains and 100 functional Megaspore?

Each microspore mother cell or pollen mother cell (PMC) on reduction division (meiosis) gives rise to 4 pollen grains. Hence, to form 100 pollen grains, 25 meiotic divisions are required.

## How many meiotic divisions are required for the formation of 400 functional Megaspore?

So, for 400 functional megaspores 400 meiotic divisions are required.

## 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 meiosis and mitotic divisions are needed for the development of 100 female gametophyte in Angiospermic plant?

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 mitotic divisions are required?

Therefore, 7 mitotic divisions are required for a single cell to make 128 cells.

## How many meiotic and mitotic divisions are required respectively to from 100 male gametes in angiosperms?

100 male gametes are developed from 100 microspores (from 25 meiotic divisions) and 100 eggs are developed from 100 megaspores (from 100 meiotic division). Hence, number of meiotic divisions necessary for 100 zygotes formation = 25 + 100 = 125.

## How many mitotic divisions are required for 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 meiotic and mitotic divisions are required for the formation of embryo sac?

2 meiotic and 1 mitotic.

## How many pollen grains are formed with 200 meiotic divisions?

Number of meiotic divisions required to produce 200/400 seeds of pea would be 250/500. 200 seeds of pea would be produced from 200 pollen grains and 200 eggs. 200 pollen grains will be formed by 50 microspore mother cell while 200 eggs will be formed by 200 megaspore mother cell so 250/500.

## How many meiotic divisions are required to produce 100 pollen grains Cyperus?

Thus, in all 200 meiotic divisons are required to produce 100 seeds.

## How many mitotic division are necessary for formation of 400 grains in wheat?

Thus 5 meiotic divisions are needed for the formation of 4 seeds and 500 meiotic divisions are required for the formation of 400 seeds.

## How many mitotic divisions are required for the formation of pollen grain?

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.

## How many meiotic divisions are required for the formation of 200 functional Megaspores?

Four meiotic divisions are required for the formation of four oospheres and only one meiotic division for the formation of four male gametes. Thus 5 meiotic divisions are needed for the formation of 4 seeds and 250 meiotic divisions are required fro the formation of 200 seeds.
