Best material for the study of mitosis in laboratory : -
A
Anther
B
Root tip
C
Leaf tip
D
Ovary
Detailed Solution
Mitosis occurs in actively dividing (meristematic) cells.
The root tip has a region of apical meristem where cells are dividing continuously, so many cells in different stages of mitosis can be seen in a squash preparation (e.g. onion root tip).
Anthers (and ovaries) are used to study meiosis; mature leaf tips have few dividing cells.
So the best material for studying mitosis in the laboratory is the root tip.
