How many times meiosis takes place for the formation of 80 wheat grains?

How many time meiosis will take place for the formation of 80 wheat grains A 100 B 80 C 40 D 99?

80 male gametes i.e. pollen grains are produced by 20 meiosis in microspore mother cells while 80 female gametes i.e. megaspores are formed by 80 meiosis in megaspores mother cells because in angiosperm plants, after meiotic division in single megaspore mother cell, four megaspores are formed but only one megaspore is …

How many meiosis are required for the formation of 100 grains of wheat?

The female gamete mother cell undergoes meiosis to produce four haploid female gametes, out of which three degenerates and only one is functional. 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.

How many meiosis are required for the formation of 80 Microspores in flowering plants?

1 meiosis produces 4 male gametes . So for 80 male gametes ,20 times meiosis is required .

How many times does meiosis take place?

Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

How many time meiosis will take place for the formation of 80 wheat grain?

For the formation of 80 zygotes we require 20 meiotic divisions forming 80 male gametes and 80 meiotic division forming 80 female gametes.

How many meiotic divisions are required for the formation of 80 pollen grains?

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 meiosis are required for 200 seeds of wheat?

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.

How many mitotic divisions are needed for 50 grains of wheat?

Thus the correct answer is option ‘A’ which is 63 meiotic divisions.

How many Microspore mother cells are responsible for the formation of 80?

So, 20 microspore mother cells are required to produce 80 male gametes in angiosperms.

How many meiosis are required for the formation of 50 embryo sac?

Therefore, 13 meiotic divisions during spermatogenesis produce 52 sperms and 50 meiotic divisions during oogenesis produces 50 eggs. Hence, the correct answer is option (B).
