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

25 meiotic divisions
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 make 200 seeds?

250 meiotic divisions
Thus 5 meiotic divisions are needed for the formation of 4 seeds and 250 meiotic divisions are required fro the formation of 200 seeds.

How do you find the number of meiotic divisions?

For calculating no. of meiotic divisions the formula is n+n/4 where n is given no. of seeds, zygote, offsprings. =250 meiotic divisions.

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

25 MMC
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 mitotic divisions are required for 400 seeds?

500 meiotic divisions
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. So, the five meiotic divisions result in four seeds thus 500 meiotic divisions result in 400 seeds.

How many pollens are wasted in 13 meiotoc divisions?

If total 13 meiotoc divisions are given, In gynoecium 10 meiotic divisions=10 eggs. In anther 3 meiotic divisions=3×4=12 pollen grains. Hence 10 egg+10 pollens=10 seeds. 12–10=2 pollens wasted.

How do you calculate the number of seeds produced by meiosis?

meiosis – No. of meiotic divisions to produce specific no. of seeds – Biology Stack Exchange If I want to produce 100 seeds. Then the no. of meiotic divisions is 125 which can be calculated by the formula x + x / 4. x = no. of seeds produced.

How many eggs are produced after 1 meiotic division in megasporangium?

Only 1 egg is produced after 1 meiotic division in the megasporangium. For production of x no. of eggs. x pollen grains and eggs are required. No. of meiotic divisions to produce x pollen grains and eggs. For producing x number of seeds (or say zygote) x number of egg cells must fuse with x number of male gametes.

How many egg cells are required to produce 480 seeds?

For making 480 seeds we will require 480 pollen [all fertile 🙂 ] plus 480 egg cell. One pollen mother cell after Meiotic division will produce 4 pollen. So 4 pollen 1 Meiosis. Then 120 Meiosis will produce 480 pollen. Next Egg mother cell after Meiotic division produces only single egg in most of the cases.
