Find out the i. Gaseous hormone from the following. ii. Hormone that could fit either of the groups, but it is largely an inhibitor of growth activities
1 Ethylene, auxins
2 Ethylene, gibberellins
3 Cytokinins, ethylene
4 Ethylene, ethylene
Explanation:
The gaseous PGR, ethylene, could fit in both groups called plant growth promoter and plant growth inhibitor, but it is largely an inhibitor of growth activities.

Kinetin -identified and crystallised by
1 Darwin
2 Cousins
3 E Kurosawa
4 Skoog and Miller
Explanation:
F. Skoog and his co-workers observed that from the internodal segments of tobacco stems the callus (a mass of undifferentiated cells) proliferated only if, in addition to auxins the nutrients medium was supplemented with one of the following: extracts of vascular tissues, yeast extract, coconut milk or DNA. Miller et al. (1955), later identified and crystallised the cytokinesis promoting active substance that they termed kinetin.
