MCQ
Genetically dwarf plants can be induced to grown tall by using:
- AAuxins
- BCytokinins
- CGibberellins
- DPhycobillins
Explanation:
Gibberellin is a plant hormone which is responsible for stem elongation by promoting cell division and elongation.
They are responsible for increased internodal length in a plant.
Auxins cause cell elongation and cell differentiation while cytokinins promote only cell division.
Phycobilins are pigments found in cyanobacteria which capture the light energy for photosynthesis in them.
