Give examples of any three physiological processes that
are regulated by hormones (3) IN PLANTS
1) Plant growth and development: Hormones such as auxins, gibberellins, and cytokinins regulate various aspects of plant growth and development. For example, auxins control cell elongation and apical dominance, gibberellins stimulate stem elongation, and cytokinins promote cell division and lateral bud growth.
2) Flowering: The hormone known as florigen regulates the flowering process in plants. It helps in the transition from vegetative growth to reproductive growth, controlling the timing and initiation of flower formation.
3) Seed germination: Hormones like gibberellins and abscisic acid play a crucial role in regulating seed germination. Gibberellins stimulate the synthesis of enzymes that break down stored nutrients in the seed, promoting germination. On the other hand, abscisic acid inhibits seed germination and maintains seed dormancy during unfavorable conditions.
