Question

Match between the following representing parts of the sperm and their functions and choose the correct option.

	Column A		Column B
A.	Head	(i)	Enzymes
B.	Middle piece	(ii)	Sperm motility
C.	Acrosome	(iii)	Energy
D.	Tail	(iv)	Genetic material

• A. A - (ii), B - (iv), C - (i), D - (iii)
• B. A - (iv), B - (iii), C - (i), D - (ii)
• C. A - (iv), B - (i), C - (ii), D - (iii)
• D. A - (ii), B - (i), C - (iii), D - (iv)

Answer 1

The correct option is B A - (iv), B - (iii), C - (i), D - (ii)

The sperm can be divided into four parts :

(i) Head : consists of an elongated haploid nucleus storing genetic material and at tip of the head is acrosome, which consist of various hydrolysing enzymes.

(ii) Neck : It is very short and consists of two centrioles.

(iii) Middle piece : It is cylindrical in human sperm and consists of mitochondria, which provides energy for movement of sperm inside female reproductive tract. The energy provided by mitochondria can help sperm survive 1-2 days.

(iv) Tail : It is long, slender and consists of cytoplasm. It helps in providing sperm with motility.

So, the correct answer is 'A - (iv), B - (iii), C - (i), D - (ii)'.
