The difference between spermiogenesis and spermiation is

  • A
    In spermiogenesis spermatozoa from sertoli cells are release into the cavity of seminiferous tubules, while in spermiation spermatozoa are formed
  • B
    In spermiogenesis spermatozoa are formed, while in spermiation spermatids are formed
  • C
    In spermiogenesis spermatids are formed, while spermiation spermatozoa are formed
  • Correct answer
    D
    In spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from sertoli cells into the cavity of seminiferous tubules

Solution

Spermiogenesis is the final stage of spermatogenesis, which sees the maturation of spermatids into mature, motile spermatozoa. The spermatid is a more or less circular cell containing a nucleus, Golgi apparatus, centriole, and mitochondria. All these components take part in forming the spermatozoon.

However, in spermiation, the spermatozoa are released from the Sertoli cells into the cavity of seminiferous tubules before they are passed through the epididymis.

Hence, the correct answer is option: 'D'.
