The number of chromosomes in the shoot tip cells of a maize plant is 20. The number of chromosomes in the microspore mother cells of the same plant shall be

Options

A. 20
B. 10
C. 40
D. 15

Answer

A

Explanation

The whole plant body of maize plant including shoot tip cells remain in diploid (2n) condition. As microspore mother cell is a reproductive organ, the chromosome number in these cells will remain same as the individual i.e. 2n = 20. These microspore mother cells are further responsible for producing male gametes i.e. haploid by reduction division.
