How many times meiosis will take place for formation of a TV grains?

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 times meiotic division will take place?

In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells, each with half the number of chromosomes as the original parent cell. The two meiotic divisions are known as meiosis I and meiosis II.

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 meiotic divisions are required to form 50 seeds?

Hence, 63 meiotic divisions are required for production of 50 seeds.

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

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 divisions are required to produce 100 seeds?

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.

Where does meiosis take place?

Explanation: Meiosis takes place in meiocytes, which forms gametes. Meiosis takes place during sexual reproduction in the formation of gametes. Some Gemmules and conidia are asexual structures, hence, meiosis does not take place. Megaspores are haploid and are formed after meiosis in the megaspore mother cell.

In which of the following meiosis takes place?

Meiosis occurs in Anther. In plants, meiosis occurs in the anthers to form pollen grains that is the male gamete, and within the ovary to form ovules. In meiosis a diploid cell divides in such a way so as to produce four haploid cells.

How many times mitotic divisions produce 512 cells?

9 mitotic division. since one mitotic division produce 2 cell.

How many meiotic divisions are needed for 80 zygotes?

Hence for all intents and functions, the general quantity of meiotic divisions had to form a hundred zygotes = 25 meiotic divisions in adult males + 100 meiotic divisions in girls = 125 which is quite vast.

How many Microspore mother cells are required to produce 1000 microspores or pollen grains?

Pollen mother cell undergoes meiotic division to produce 4 pollen grains. So, for generation of 1000 pollen grains, 1000/4 = 250 pollen mother cells undergo meiotic division.

How many 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 meiotic divisions are required to form 400 seeds of peas?

Complete answer:

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

How many meiotic divisions are required to produce 120 seeds?

1 meiotic division refers to the formation of 4 microspores from one microspore mother cell. Each microspore develops into a pollen grain( male gamete). So, for getting 120 male gametes, we require= 120/4 = 30 meiotic divisions.

How do you calculate division in meiosis?

Meiosis is a specific type of cell division used ONLY to produce sperms and oocytes. Formula of meiosis: (2n × 2) / 4.
