Solution
The correct option is B Spermatogonia,Spermatocytes,Spermatids,Spermatozoa
Spermatogonia which constitute the germinal epithelium of the seminiferous tubules divide mitotically to form primary spermatocytes which undergo meiosis to form secondary spermatocytes. These cells then undergo mitosis to form spermatids which still resemble spermatogonia cells. Spermatids then finally undergo spermiogenesis, in which the they are stripped down and remodelled to form highly specialised spermatozoa.

(a) About 300 million spermatozoa may be present in a human male ejaculation at one time. Calculate how many spermatocytes will be involved to produce this number of spermatozoa.Join BYJU'S Learning Program
