Model Answer
(a) Components and Functions of Male Reproductive System:
| Component | Function |
|---|---|
| Testes | Produce sperms (germ-cells); secrete testosterone |
| Vas deferens | Carries sperms from testes towards the urethra |
| Seminal vesicles & Prostate gland | Add secretions to sperms, forming semen; provide nutrition and ease transport |
| Urethra | Common passage for sperms and urine to exit the body |
| Penis | Delivers sperms into the female reproductive tract |
(b) Two effects of testosterone:
- Regulates the formation of sperms in the testes.
- Brings about changes in appearance at puberty in boys (e.g., new facial hair, deeper voice).
(c) Difference between vas deferens and urethra:
The vas deferens carries sperms from the testes and unites with the tube from the urinary bladder — it transports sperms only. The urethra is the final common passage that carries both sperms and urine out of the body.

Explanation
- (a) Examiners expect all major parts listed with a distinct function for each. The table format saves space and is perfectly acceptable in CBSE boards.
- (b) Both effects are directly stated in the passage — "regulating the formation of sperms" and "changes in appearance seen in boys at puberty." Never add effects not in the source.
- (c) The key distinction is sperms only (vas deferens) vs. sperms + urine (urethra). This one-line difference is all that is needed for a differentiation question of this weight.
