Cytokinins are predominantly present in:
A. Permanent tissues
B. Meristematic tissues
C. Endodermis
D. Cortical region
Answers
Cytokinin are predominantly found in the meristematic tissue which is present in those places where growth of a plant takes place.
Meristematic They promote differentiation and cell growth because they are a kind of phytohormones.
They regulate supplementary growth of the bud and apical dominance.
The biosynthesis of the cytokinin is regulated by the auxin.
Farmers usually use them to increase the rate of crop growth.
'Cytokinins' are predominantly present in "Meristematic tissues".
EXPLANATION:
Cytokinins are class of plant growth substance called phytohormone which promotes the division or cytokinesis, they are found in roots and shoots of plant, especially in meristematic tissue responsible for cell growth, they regulate the growth bud and apical dominance. They are compound with structure close to adinine. The most common form is zeatin. The other one include 'dihydrozeatin', 'isopentenyladenine' or 'benzyladenine'. They are found almost all in plant tissue. Found in abundant in root tip xylem and young leaves.
