*AFNS / AMC Tip:* Chapter 15 is frequently tested in AFNS:
`Plant hormones: Auxin=elongation | Gibberellin=germination | Cytokinin=cell division | ABA=anti-growth | Ethylene=ripening`
`Growth: Meristematic, Elongation, Differentiation phases | S-curve`
`Human: Thyroxine=metamorphosis in frog | Growth hormone from pituitary`
`Photoperiodism = flowering response | Vernalization = cold treatment`
