## 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 the formation of 100 matured embryo sac?

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

## How many meiotic divisions are required to produce 100 seeds in most angiosperms?

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

**2 meiotic and 1 mitotic**.

## How many meiotic divisions are required for 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 needed for formation 100 grains of wheat?

So, for the formation of 100 grains of wheat, a total of 100 female gametes are needed, which means a total of **100 meiotic divisions** are needed. Hence, including the number of meiotic divisions in both the male and female sex organs of the plant, a total of 125 divisions would give rise to 100 wheat grains.

## How many pollen are required if 100 seeds are to be formed in an Angiospermic plant?

The primary sporogenous cell gives rise to microspore mother cells or pollen mother cells. Each microspore mother cell on reduction division gives rise to 4 microspores or pollens. So for the formation of 100 pollen grains, **25 MMC** are required.

## How many meiotic division would be required to produce 101 female Gametophytes in an angiosperm A 101 B 26 C 127 D none of these?

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.
