The difference between spermiogenesis and spermiation is

  1. in spermiogenesis spermatids are formed, while in spermiation spermatozoa are formed
  2. in spermiogenesis spermatozoa are formed, while in spermiation spermatids are formed
  3. in spermiogenesis spermatozoa from Sertoli cells are released into the cavity of seminiferous tubules, while in spermiation spermatozoa are formed
  4. in spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from Sertoli cells into the cavity of seminiferous tubules

Answer

(4) in spermiogenesis spermatozoa are formed, while in spermiation spermatozoa are released from Sertoli cells into the cavity of seminiferous tubules

Solution

As per NCERT, the spermatids are transformed into spermatozoa (sperms) by the process called spermiogenesis.

After spermiogenesis, sperm heads become embedded in the Sertoli cells, and are finally released from the seminiferous tubules by the process called spermiation.

Spermiogenesis forms spermatozoa, while spermiation releases them from the Sertoli cells into the cavity of the seminiferous tubules.

Fertilisation in humans is practically feasible only if

  1. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the cervix
  2. the sperms are transported into cervix within 48 hrs of release of ovum in uterus
  3. the sperms are transported into vagina just after the release of ovum in Fallopian tube
  4. the ovum and sperms are transported simultaneously to ampullary-isthmic junction of the Fallopian tube.

Select the incorrect statement.

  1. LH and FSH decrease gradually during the follicular phase.
  2. LH triggers secretion of androgen from the Leydig cells.
  3. FSH stimulates the Sertoli cells which help in spermiogenesis.
  4. LH triggers ovulation in ovary.
