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 post meiotic mitotic divisions?
2 meiotic and 1 mitotic.
How many mitotic divisions are required to produce 100 seeds?
Only one fuses with egg to produce zygote, becomes seed containing embryo. To form 100 seeds, 100 generative cells are required which are ptoduced by 100 mitotic divisions in microspore.
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 mitotic and meiotic divisions are required to form a megaspore?
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).
How many meiotic and mitotic divisions are required for development of female gametophyte?
The female gametophyte is derived from functional megaspore. Thus to produce 101 female gametophytes, 101 meiosis divisions are required that will occur in 101 megaspore mother cells.
How many meiotic divisions are needed for 160?
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 mitotic divisions are required to produce 50 seeds?
Thus, in order to produce 50 mature ovules, 50 megaspore mother cells will undergo 50 meiotic divisions, one meiosis per megaspore mother cell. This takes the requirement of 50 (in megaspore mother cells) + 13 (in microspore mother cells), i.e., 63 meiotic divisions.
How many mitotic divisions are necessary?
Hence 7 mitotic divisions cell needed for a single cell to make 128 cells.
How many meiotic divisions are needed for 100 Megaspore?
– The megaspore (ovule) is also developed by the meiotic division. For the development of one megaspore one meiotic division is required. So, for the development of 100 megaspores 100 meiotic division is required.
How many meiotic divisions are required for?
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.
