How many mitotic divisions are required for the formation of mature male gametophyte in angiosperms?

Hence, one meiotic division and two mitotic division are required for the formation of fully mature male gametophyte from microspore mother cell in angiosperm.

How many meiotic and mitotic divisions are required for the formation of male gametophyte?

2 meiotic and 2 mitotic.

How many mitotic divisions are needed for male gamete?

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 divisions are necessary for formation of 180 sperms?

A zygote is diploid (2n) in nature and is formed during the fertilization of male gamete with the female gamete. For 50 zygotes, 50 male and 50 female gametes are required. Therefore, 13 meiotic divisions during spermatogenesis produce 52 sperms and 50 meiotic divisions during oogenesis produces 50 eggs.

How does development of male gametophyte takes place?

The development of the male gametophyte occurs in both stamen and in the female reproductive part. The microspore mother cell is all the way converted into a sperm cell which is a final male gametophyte. Complete step by step answer: … The pollen grain has two cells: large generative cell and one small tube cell.

THIS IS INTERESTING:  Is diploid half or full?

How many mitotic divisions are needed for 100 cells?

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

How many meiotic and mitotic divisions are required for the development of 16 male gametes?

So the correct answer is ‘2‘.

How many mitotic and meiotic divisions are required to form a Megaspore?

Comparative Reproduction

From the remaining functional megaspore, the megagametophyte (also known as female gametophyte or embryo sac) develops by three mitotic divisions, at the mature stage consisting of 8 nuclei and 7 cells (one egg cell, two synergids, one central cell and three antipodals).
