Cytokinin And Active Growth.

Question 1

What are cytokinin?

Answer 1

Plant hormone drives from adenine

Question 2

Why are they named cytokinins?

Answer 2

Because of their role in cytokinesis a stage of cell division.

Question 3

Where are cytokinins found?

Answer 3

Roots, embryos, and fruits, where cell division is actively occurring.

Question 4

What will happen if cytokinins is not present in plant?

Answer 4

Germination Will stop, cell division will not be regulated In roots and shoots

Question 5

What will happen if Zeatin is sprayed on meristem during early stages?

Answer 5

It will activates formation of lateral branching on stem, and increase branching, this result in bushier more productive monocot such as rise and other grains.

Question 6

What will form ( root or callus or shoot) when auxins conc =2 and kinetin conc= 0.2?

Answer 6

Callus.

Question 7

What will form ( root or callus or shoot) when auxins conc =0.2 and kinetin conc= 1?

Answer 7

Shoot

Question 8

What will form ( root or callus or shoot) when auxins conc =2 and kinetin conc= 0.02?

Answer 8

Roots

Question 9

What will form ( root or callus or shoot) when auxins conc =0 and kinetin conc= 0.2?

Answer 9

No growth

Question 10

Explain the role of antagonistic hormone control in seedlings and lateral buds

Answer 10

If the concentration of kinetin was increased, auxin level decreased, and shoots formed.
• When kinetin was low, auxin was high, and roots are formed.
