Study the following diagrams showing various stages of binary fission in Amoeba:
The correct sequence of these diagrams should be:
(A) I, IV, III, II, V
(B) I, III, IV, II, V
(C) I, II, IV, III, V
(D) I, II, III, IV, V
उत्तर
During binary fission, the nucleus of the parent cell elongates and divides initially. A constriction starts appearing on the cell membrane. It starts widening and finally divides the parent cell into two almost equal halves (daughter cells). The daughter cells are identical to the parent cell.
Hence, the correct option is B.

How can you grow money plant by vegetative propagation?
When the branches of a plant growing in the field are pulled towards the ground and a part of them is covered with moist soil (leaving the tips of the branches exposed above the ground), then after some time new roots develop from the parts of branches buried in the soil. On cutting these branches from the parent plant, new plants are produced from the cut parts of branches which had developed roots.
