Detailed explanation-1: -The whole plant body of maize plant including shoot tip cells remains in diploid (2n)condition. As the microspore mother cell is a part of reproductive organ, the chromosome number in these cells will remain same as the individual. i.e., 2n=20.
Detailed explanation-2: -The number of chromosomes in the shoot tip cells of a maize plant is 20.
Detailed explanation-3: -Hence, in maize, the chromosome number in the diploid meiocytes (2n) is 20. The gametes or the reproductive cells (n) have 10 chromosomes.
Detailed explanation-4: -The body of a maize plant has a diploid state I.e. (2n) state. The microspore mother cell is the part of the reproductive system; hence it also remains in a diploid state. This shows that the number of chromosomes in the microspore mother cells of the same plant shall be 20.
Detailed explanation-5: -So, the correct option is ‘63’.
