Question

Assertion In mitosis, two identical cells are produced from a single cell and karyokinesis is followed by cytokinesis.
Reason Cytokinesis is of two types, i.e. by cell-furrow method and cell plate method.
A. Both A and R are true and R is the correct explanation of A
B. Both A and R are true, but R is not the correct explanation of A
C. A is true, but R is false
D. A and R are false

Answer 1

Correct Answer - B
Mitosis is the process by which a cell nucleus divides (karyokinesis) to produce two daughter nuclei containing identical sets of chromosomes to the parent cell. It is usually followed immediately by division of cytoplasm (cytokinesis) to form two daughter cells. In plants, cytokinesis occurs by cell-plato method whereas in animals, it occurs by cell furrow method.
