Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Plants have rapid cell division within their meristematic tissue, such as is found at the root tips. What kind of cell division allows a plant to grow?

A	Binary fission
B	Mitosis
C	Meiosis
D	Replication

Explanation:

Detailed explanation-1: -It is because of the meristematic cells that are situated in the tip of the roots that render the most desirable and suitable raw material to study the different stages of mitosis. Onion is a monocot plant. Monocotyledonous plants possess large chromosomes that are clearly visible. Hence, their root tips are used.

Detailed explanation-2: -Apical Meristem These are present at the tips of the roots and shoots and helps in the increase of the height of the plants. Various cell divisions facilitate the growth of the cells in the roots and shoots and help in cellular enlargement.

Detailed explanation-3: -Root tip as compared to the leaf tip is the best material to study mitosis. Root tip is a rapidly growing part of a plant body and thus many cells will be in different stages of mitosis.

Detailed explanation-4: -The key to continued growth and repair of plant cells is meristem. Meristem is a type of plant tissue consisting of undifferentiated cells that can continue to divide and differentiate.
