Question

Give an example of a plant hormone that promotes growth.

Answer 1

Auxin:

1. Auxins are plant hormones that stimulate stem elongation whilst inhibiting the formation of lateral buds (keeps apical dominance).
2. They are fashioned in the stem, buds, and root tips.
3. Auxin travels to the darker side of the plant, causing cells to grow larger than equivalent cells on the lighter side.
4. Aids in the molecular department and xylem differentiation
5. Induces parthenocarpy, or the formation of fruit without fertilization, as in tomatoes.
