Question

What is the number of chromosomes in the following cells of human male ?
a) Spermatids
b) Sertoli cells

Answer 1

Answer:

spermatitd 23

sertoli 23

Answer 2

Explanation:

spermatids

23 chromosomes

23 chromosomes. Because it is a gamete and gametes are haploid i.e. half the number of chromosomes. Since humans have 46 chromosomes so, 23 chromosomes are present in spermatids which will later make sperms.

b) Sertoli cells:Cell type ploidy/chromosomes in human Process entered by cell

primary spermatocyte diploid (2N) / 46 spermatidogenesis (meiosis I)

two secondary spermatocytes haploid (N) / 23 spermatidogenesis (meiosis II)

four spermatids haploid (N) / 23 spermiogenesis

four functional spermatozoids haploid (N) / 23 spermiation
