Question

How many pollen mother cells should undergo reduction division to produce 80 pollen grains
(A) 20
(B) 32
(C) 16
(D) 8​

Answer 1

Answer:

How many pollen mother cells should undergo meiotic division to produce 64 pollen grains? Solution : Each pollen mother cell (PMC), by a meiotic division, gives rise to a group of four haploid microspores. Thus, 16 pollen mother cells undergo meiotic divisions to produce 64 pollen grains.

Answer 2

20 pollen mother cells should undergo reduction division to produce 80 pollen grains

A) 20

1 parent mother cell(PMC) , by meiotic division,

gives rise to a gropu of 4 haploid daughter cells.

1 pmc = 4 daughter cells

¼ pmc = 1 daughter cells

80/4 pmc = 80 daughter cells

20 pmc
