Plant growth hormones extracted from a fungus and a fish are respectively
Options
- AGibberellins and zeatin
- BEthylene and cytokinin
- CAuxin and 2, 4-D
- DGibberellin and kinetin
Correct answer
D. Gibberellin and kinetin
Step-by-step solution
Gibberellins is the plant hormone that was produced from the fungus Gibberella fujikuroi after isolation and therefore the fungus is named gibberellin. This hormone is a plant growth regulator and is involved in stem elongation, dormancy, and various other processes involving plant growth. Kinetin is also a plant hormone that helps in plant growth by promoting cell division. This hormone was first isolated from the DNA of herring fish.
