Q1. [3] deep thorough-understanding
The sperms produced in the testes are not immediately capable of fertilising an egg on their own. Explain what additional contributions are made to the semen before it leaves the male reproductive system, and analyse why these contributions are essential for the sperms to function effectively.

Model Answer
Sperms produced in the testes are tiny bodies containing mainly genetic material and a long tail. As they travel through the vas deferens, glands like the seminal vesicles and the prostate gland add their secretions to form semen. These secretions are essential because:
- They provide a fluid medium that makes transport of sperms easier.
- They provide nutrition to the sperms, enabling them to remain active and move towards the female germ-cell.
Without these secretions, sperms cannot survive or travel effectively to reach and fertilise the egg.

Explanation
- Examiners expect you to name both glands (seminal vesicles and prostate) — missing either loses a mark.
- Two functions must be stated: transport (fluid medium) and nutrition. These are the exact words used in the textbook, so use them.
- The question says "analyse why essential," so link the secretions back to sperm function (movement + survival). A one-line conclusion tying it together scores the third mark.
