Auxin
This question was previously asked in
UPSC CDS-1 – 2021
The plant hormone to suggest for increasing cell division among plants would be Cytokinin.
Cytokinins are a class of plant hormones that promote cell division (cytokinesis) in plant roots and shoots. They are involved in cell growth, differentiation, and delay of senescence.
Auxins primarily promote cell elongation, although they interact with cytokinins in regulating cell division and differentiation. Gibberellins promote stem elongation and germination. Abscisic acid is primarily involved in inhibiting growth and promoting dormancy and stress responses.
