Science — CBSE Class 10 board question

(a) The testes are located outside the abdominal cavity in the scrotum because sperm formation requires a temperature slightly lower than normal body temperature. The scrotum provides this cooler environment, which is essential for the production of viable germ cells (sperms).

(b) The seminal vesicles and prostate gland secrete fluids that provide nutrition to the sperms and make the medium alkaline, which facilitates their transport and motility. This ensures that the sperms remain active and functional while travelling towards the egg.

• For (a), the key point is temperature — testes need ~2°C below body temperature for sperm production. Examiners expect this specific reason.
• For (b), name the glands (seminal vesicles, prostate), state their functions: nutrition + alkaline medium. These points come from the reproductive system topic; though not detailed in the given passage, this is standard CBSE textbook content for this chapter.
