Question

With reference to human sperm, match the List-I with List-II.

List-I		List-II
1.	Head	p.	Filled with enzyme
2.	Acrosome	q.	Contains mitochondria
3.	Middle piece	r.	Sperm motility
4.	Tail	s.	Contains haploid nucleus

Choose the correct option from the following :

• A. 1-r, 2-q, 3-s, 4-p
• B. 1-s, 2-p, 3-q, 4-r
• C. 1-s, 2-r, 3-p, 4-q
• D. 1-q, 2-s, 3-r, 4-p

Answer 1

The Correct Option is B

1. Head: The head of the sperm contains the haploid nucleus (s).

2. Acrosome: The acrosome is filled with enzymes that help the sperm penetrate the egg (p).

3. Middle piece: The middle piece of the sperm contains mitochondria to provide energy for movement (q).

4. Tail: The tail of the sperm is responsible for sperm motility (r).

The correct answer is (B) : 1-s, 2-p, 3-q, 4-r.

Answer 2

The correct answer is: (B) 1-s, 2-p, 3-q, 4-r.

Let's match the components of the human sperm with their functions:

• 1. Head – The head of the sperm contains the haploid nucleus, which carries the genetic material for fertilization. Therefore, the match is 1-s: Contains haploid nucleus.
• 2. Acrosome – The acrosome is a cap-like structure on the head of the sperm that is filled with enzymes. These enzymes help the sperm penetrate the egg during fertilization. Therefore, the match is 2-p: Filled with enzyme.
• 3. Middle piece – The middle piece of the sperm contains mitochondria that provide energy for sperm motility. Therefore, the match is 3-q: Contains mitochondria.
• 4. Tail – The tail of the sperm is responsible for sperm motility, allowing the sperm to swim towards the egg. Therefore, the match is 4-r: Sperm motility.

Thus, the correct matching is 1-s, 2-p, 3-q, 4-r.
