Answer the following questions based on human male reproductive system :(a) In which organ sperms are formed ?(b) What is the length of a sperm ?(c) What is the work of vas deferens ?(d) By which type of cell division, sperms are formed ?(e) Name any…

Answer:

(a) Sperms are formed in the testes (in the seminiferous tubules).

(b) A sperm is about 60 micrometres (0.06 mm) long; it has a head, a middle piece and a tail.

(c) The vas deferens carries sperms from the epididymis towards the urethra (through the ejaculatory duct); on the way they receive secretions of the seminal vesicles and prostate gland, which form semen.

(d) Sperms are formed by meiosis (reductional cell division), so each sperm has half the number of chromosomes (22 + X or 22 + Y).

(e) Prostate gland and urethra (also the penis).
