Functions not induced by Cytokinins i. Production of leaves ii. Production of chloroplasts iii. Nutrient mobilization iv. Leaf senescence v. Xylem differentiation vi Synthesis of carotenoids Options
1 i, ii, iii
2 iv, v, vi
3 ii, iv, $v$
4 iii, iv, vi
Explanation:
B Cytokinins functions induced by production of leaves, production of chloroplasts, nutrient mobilization. Leaf senescence has the important function of recycling nutrients, mostly nitrogen to growing and storage organs of the plant.

In a garden, the gardner cut the apical bud of Lawsonia (Mehandi) because
1 The length should be limited in Lawsonia
2 Due to the cutting of apical bud the effect of auxins decreases and lateral bud grows and forms dense appearance that is why it can give a definite shape
3 Other apical bud grows quickly due to cut of apical bud
4 Due to the cutting of apical bud effect of ethylene decreases and plant growth rapidly
Explanation:
B In a garden, the gardner cut the apical bud of Lawsonia (Mehandi) because of due to the cutting of apical bud the effect of auxins decreases and lateral bud grows and forms dense appearance that is why it can give a definite shape.

Artificial application of auxins like IAA, IBA and NAA to unpollinated pistils can form
1 Fruits with much flash
2 Larger fruits
3 Sweet fruits
4 Seedless fruit
Explanation:
D Artificial application of auxins like IAA, IBA and NAA to unpollinated pistils can form seedless fruits. Auxin is a plant hormone that is produced in the stem tip that help cell elongation. Auxins also promote flowering and prevent dropping of fruits and leaves at early stage.

ABA closes stomata but which hormone encourages them to open?
1 GA
2 Auxin
3 Cytokinin
4 Ethylene
Explanation:
C ABA closes stomata but cytokinin hormone encourages them to open. Cytokinin also help in plants growth and cytokinesis in different parts of the plant. This hormone controls the opening of stomata. It also has a major role in plant pathogenesis by including disease resistance to certain pathogens.
