Biology Question on Plant Growth Regulators
Natural cytokinins are synthesized in tissue that are
A
senescent
B
dividing rapidly
C
storing food material
D
differentiating
Answer
differentiating
Explanation
Solution
Cytokinins are produced in actively growing tissues such as embryos, developing fruits and roots. Cytokinins have so far been extracted from coconut milk (liquid endosperm), tomato juice, etc. In conjugation with auxins they stimulate cell division even in permanent tissue. The root or shoot differentiation depends upon the cytokinin auxin ratio.
