Match items in Column-I with Column-II and choose the correct option. Column-I Column-II a) Acrosome i) Contains numerous mitochondria which produce energy b) Head ii) Facilitates sperm motility c) Middle piece iii) Filled with enzymes that help in fertilization d) Tail iv) Contains elongated haploid nucleus
Options
- Aa - iii, b - i, c - iv, d – ii
- Ba - iv, b - ii, c - iii, d – i
- Ca - iii, b - ii, c - iv, d – i
- Da - iii, b - iv, c - i, d – ii
Correct answer
D. a - iii, b - iv, c - i, d – ii
Step-by-step solution
The acrosome is a cap-like structure present at the anterior end of the sperm head and is filled with enzymes that help in the fertilization of the ovum. Thus, a matches with iii. The head of the sperm contains an elongated haploid nucleus containing the genetic material. Thus, b matches with iv. The middle piece possesses numerous mitochondria, which produce energy for the movement of the tail. Thus, c matches with i. The tail facilitates sperm motility, which is essential for fertilization. Thus, d matches with i
