Dear Student


Ans 4. Option (4) is correct: Spermatogonia - Primary spermatocytes - Secondary spermatocytes - Spermatozoa.

Ans 5. Option 2 is correct:
 Seminiferous tubules - Epididymis - Vas deferens - Urethra - Vagina - Uterus - Fallopian tubes

Sperms are produced inside the testes of male reproductive system. The process through which sperms are produced is known as spermatogenesis. Sperms are produced inside coiled structures called seminiferous tubules present in testes. By meiotic cell division sperm mother cells produce spermatozoa or sperm. A structure called epididymis is present where newly formed sperms are stored and developed. The mature sperm then travel from epididymis through vas deferens into the ejaculatory duct. From ejaculatory duct mixing with other secretion comes out of the body.
Semen is a fluid in which sperms travel during ejaculation. 
During sexual intercourse, the sperms enter into the vagina of the female and swim through the uterus (womb) to enter into the fallopian tubes (oviducts).
