Question

Two cytokinins are kinetin and Zeatin. What is the difference bwteen the two ?

A

Kinetic is the active form of zeatin

B

Zeatin is the active from of kinetic

C

Zeatin is a synthetic cytokinin and kinetin is naturally occurring

D

Zeatin is a naturally occurring plant cytokinin, kinetin is not​

Answer 1

Answer:

Zeatin is a synthetic cytokinin and kinetin is naturally occurring

Answer 2

• The structure of cytokinin is similar to adenine.
• Kinetin was the first artificial cytokinin to be found. The isolation was done herring sperm. It promotes cell division.
• The naturally commonly occurring cytokinin is zeatin.
• They are usually present in most of the plant tissues.
• Thus, Kinetin is artificial cytokinin whereas zeatin is naturally occurring cytokinin.

Hence, the correct option is (D ) Zeatin is a naturally occurring plant cytokinin, kinetin is not.
