Give examples of any three physiological processes that

are regulated by hormones IN PLANTS

1 answer

1. Germination: Hormones such as gibberellins regulate the process of seed germination in plants. They promote cell elongation and division, leading to the growth of the root and shoot systems from the seed.

2. Flowering: Hormones like auxins and cytokinins play a crucial role in regulating the flowering process in plants. Auxins promote flowering, while cytokinins delay it. The balance between these hormones determines when and how a plant will flower.

3. Senescence: Ethylene is a hormone that regulates the senescence (aging) process in plants. It triggers the breakdown of chlorophyll and other cellular components, leading to the yellowing and wilting of leaves. Ethylene also promotes the shedding of fruits and leaves.
