You are given a tissue with its potential for differentiation in an artificial culture. Which of the following pairs of hormones would you add to the medium to secure shoots as well as roots?

1.  IAA and gibberellin

2.  Auxin and cytokinin

3.  Auxin and abscisic acid

4.  Gibberellin & abscisic acid

Natural cytokinins are synthesized in tissue that are:-

(1) senescent

(2) dividing rapidly

(3) storing food material

(4) differentiating

Cytokinin does not help in:

1. Lateral shoot growth
2. Overcoming apical dominance
3. Adventitious shoot formation
4. Promoting leaf senescence

Kinetin (cytokinin) was first discovered as a breakdown products of 

1. DNA 

2. t-RNA

3. Spindle fibres 

4. m-RNA

Find the incorrect statement.

F. Skoog and his co-workers observed that

1. Callus proliferated only if Auxin is there

2. Callus proliferated only if Auxin + extracts of vascular tissue was there

3. Callus proliferated only if Auxin + Yeast extract was there

4. Callus proliferated only if Auxin + coconut milk/DNA was there
 

Coconut water contains

1. ABA

2. auxin

3. cytokinin

4. gibberellin
