How many pollen mother cell S is are required for the formation of 8 male gametes in a typical angiosperm?
The pollen mother cell is a diploid cell that gives rise to the haploid reproductive cells or the gametes. The pollen grain contains the gametes. The pollen mother cell or the Microspore mother cell undergoes meiosis to form four male gamete containing structures or the microspores/pollen grains.
How many male gametes can 4 pollen mother cells produce?
The answer is 16* because one pollen mother cell may produce 4 gametes.
When a pollen grain is shed at the 3 celled stage which three cells are found?
When a pollen grain is shed at the three celled stage, it contains a vegetative cell and two male gametes.
How many male gametes can be produced?
During fertilization, a spermatozoon and ovum unite to form a new diploid organism. Gametes carry half the genetic information of an individual, one ploidy of each type, and are created through meiosis, in which a germ cell undergoes two fissions, resulting in the production of four gametes.
How many pollen grains mother cells are required for the formation of 200 male gametes?
Now, 1 meiotic division in male produces 4 gametes. So, in order to make 200 male gametes, there will be 50 meiotic divisions in male. In total there are 200+50=250 meiotic divisions required to produce 200 seeds.
How many male gametes are possible from 10 Microspore mother cells?
Each microspore mother cell yields 4 pollen grains in a single meiosis. Thus it provides 40 pollen grains as a result of 10 meiotic divisions in microspore mother cell.
How many maximum male gametes can be formed by a microspore mother cell?
So, one microspore mother cell produces four pollen grain and each pollen grain produces two gametes, there eight gametes are produced by one microspore mother cell.
How many Meiosiss are needed for 64 male gametes?
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 needed for 64 Pollengrains?
1 meotic division to produce 4 polen grains.. to produce 64 pollen grains > 16 meotic divisions are required…
