Detailed explanation-1: -The stem cells are the somatic cells. So if the stem cell of the plant has 24 chromosomes. 2n = 24, now we know the gametes are haploid and they contain half the number of chromosomes present in somatic cells. Therefore, gametes will have n = 12 i.e. gametes will have 12 chromosomes.
Detailed explanation-2: -If any organism has a haploid of 24 chromosomes, the total number of chromosomes in its diploid stage will be 48 chromosomes ( 24x2)
Detailed explanation-3: -This is the right answer as the diploid set of a haploid of 24 chromosomes will be 24×2=48. So, the total number of chromosomes in an organism with a haploid number of 24 chromosomes will be 48.
Detailed explanation-4: -Somatic cells are haploid and sex cells(gametes) are diploid. If the number of chromosomes in the somatic cells of an organism is 24, then the number of chromosomes in its gametes will be 12.
Detailed explanation-5: -Gametes are haploid cells i.e. they contain half the number of chromosomes of the normal somatic cells of the body. Somatic cells are diploid in nature. Since the gamete has 7 chromosomes, the somatic cells will have twice this number i.e. 14 chromosomes. Q.
