Current Question (ID: 12879)

Question:

Match the Following: Column I A. IAA B. ABA C. Ethylene D. GA E. Cytokinin Column II 1. Herring sperm DNA. 2. Bolting 3. Stomatal closure 4. Weed-free lawns 5. Ripening of fruits. Codes

Options:

1. A-4, B-3, C-5, D-2, E-1
2. A-5, B-3, C-4, D-2, E-1
3. A-4, B-1, C-4, D-3, E-2
4. A-5, B-3, C-2, D-4, E-4

Solution:

A. IAA Weed free lawn 2-4 D and synthetic indole acetic acid kill the broad leaf weeds. Thus used as a weedicides. B. ABA-Stomatal closure ABA is a stress hormone Under water stressed conditions, it shuts down stomata to reduce the rate of transpiration. C. Ethylene a gaseous hormone is responsible for ripening of fruits. D. GA Gibberellic acid does the phenomenon of bolting i.e., when sprayed on the plant, it increases the internodal region of stem, stem thus making a plant extremely tall. E. Cytokinin was isolated from herring sperm DNA for the first time. Other options are incorrect
