Question: 110. Match List-I with List-II.
| List-I | List-II |
|---|---|
| A. Head | I. Enzymes |
| B. Middle piece | II. Sperm motility |
| C. Acrosome | III. Energy |
| D. Tail | IV. Genetic material |
Choose the correct answer from the options given below:
(1) A-IV, B-III, C-I, D-II
(2) A-IV, B-III, C-II, D-I
(3) A-III, B-IV, C-II, D-I
(4) A-III, B-II, C-I, D-IV
Answer: Option (1)
Explanation:
The head of the sperm contains the nucleus, which carries the genetic material.
Therefore, Head matches with genetic material (IV).
The middle piece of the sperm contains numerous mitochondria.
Mitochondria provide energy required for movement of the sperm.
Thus, Middle piece matches with energy (III).
The acrosome is a cap-like structure present over the head of the sperm.
It contains enzymes that help the sperm penetrate the egg during fertilization.
Hence, Acrosome matches with enzymes (I).
The tail of the sperm is responsible for movement.
Therefore, Tail matches with sperm motility (II).
So, the correct matching is A-IV, B-III, C-I, D-II.
