Solution


Q.

In the following figure different stages of binary fission in Amoeba are depicted, which are not in proper sequence.
 

 

The correct sequence is :
1 II, III, IV, I  
2 I, II, IV, III  
3 III, IV, II, I  
4 I, III, IV, II  

Ans.

(1)

In Amoeba, binary fission is an asexual method of reproduction. (II) represents the parent cell, which replicates the genetic material as shown in (III). The cytoplasm divides after karyokinesis, resulting in two cells (IV). The two cells illustrated in (I) are the daughter cells that result from binary fission.
