Text Solution

Verified by Experts

The correct Answer is:
B
Cytokinesis is the divisio of protoplast of a cell into two daughter cells after karyokinesis (nuclear division). Normally, cytokinesis starts towards the middle anaphse and is completed simultaneously with the telophase. In plants, cytokinesis occurs by cell plate method in which cell plate grown centrifugally. In animals, it takes plaec by cleavage. cleavage progresses centripetally.
