Root hairs develop from the region of
1 Maturation
2 Elongation
3 Root cap
4 Meristematic activity
Explanation:
A Root has three prominent regions- (i) Region of maturation. (ii) Region of elongation. (iii) Region of meristematic activity. - Root hairs develop from the region of maturation. Certain epidermal cells from this region from fine and delicate, thread-like structure called root hairs. It helps in the absorption of water and minerals. Root hair are long tubular-shaped outgrowth from root epidermal cells.

Best material for the study of mitosis in laboratory is: -
1 Anther
2 Root tip
3 Leaf tip
4 Ovary
Explanation:
B Root tip as compared to the leaf tip/anther/ovary is the best material to study of mitosis. Root tip have active meristematic zone where cells divide mitotically leading increase in length of the root. So, the root tips are the most commonly used for studying mitosis. Example :- (Allium cepa, Allium sativum) Root tip.

Quiescent centre theory was proposed by:
1 Nageli
2 Schmidt
3 Hanstein
4 Clowes
Explanation:
D Quiescent centre theory was proposed by a British biologist Frederick Albert Lionel Clowes (F.A.L. Clowes) in 1961 in Maize and observed an inactive center in between root cap and active meristematic region. The quiescent centre, play a crucial role in maintain the surrounding stem cells and promoting root growth.
