How many mitotic divisions are required for formation of male gametes from a mature male gametophyte in flowering plants?
two mitotic division
One meiotic and two mitotic division.
How many meiotic and mitotic divisions are required for the formation of male gametophyte from pollen mother cell *?
One meiotic and two mitotic divisions
These processes are necessary for the complete development of male gametophyte from Pollen mother cell. One meiotic and two mitotic divisions.
How many meiotic and mitotic divisions are required respectively to from 100 male gametes in angiosperms?
100 male gametes are developed from 100 microspores (from 25 meiotic divisions) and 100 eggs are developed from 100 megaspores (from 100 meiotic division). Hence, number of meiotic divisions necessary for 100 zygotes formation = 25 + 100 = 125.
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 divisions are required to produce male gametes?
100 mitotic divisions
So, to produce 100 male gametes, 50 pollen grains and 100 mitotic divisions are required.
How many mitotic divisions are required for the formation of 2 male gametes?
Two meiotic divisions and one mitotic division.
How many total meiotic and mitotic divisions are required?
2 meiotic and 1 mitotic.
How many mitotic divisions are required for the formation of 100 pollen grains?
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 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.
How many mitotic divisions are required for the formation of?
3 mitotic divisions are required for the formation of mature embryosac.
How many mitotic divisions are required for the formation of female gametophyte?
The number of meiotic and mitotic divisions necessary for development of female gametophyte in angiosperms is 1 meiosis and 3 mitosis.
How many mitotic divisions are required for the formation of two male gametes from one pollen grain?
two mitotic
Question : In angiosperms, formation of two male gametes from a pollen grain involves- divisions. Only two mitotic.
