Expert Solution

Step 1

The plant hormones are of five types:

Gibberellins
Cytokinins
Ethylene
Abscisic acid
Auxin

The amino acid tryptophan gives a plant hormone which is auxin. An auxin helps in cellular regulation. Auxin plays a major role in:

Shoot elongation
Cell division
Cell differentiation
Regulate the growth of the plant
