Q.1. What are plant hormones?
Plant hormones- These are also called phytohormones. Plant hormones are the chemical substance that helps in the growth of the plant(height), flowering, and also the development of plants and their response to the environment.
For example; auxins, gibberellins, and cytokinins are some phytohormones.
Auxin is a plant hormone that controls growth and development in plants. It plays a key role in processes like cell elongation, maintaining apical dominance, forming roots, and responding to environmental cues such as light and gravity (phototropism and gravitropism)
Gibberellins are a class of plant hormones that control growth and development. They play a key role in processes like seed sprouting, stem growth, leaf enlargement, flowering, and the formation of fruits.
Cytokinins are plant hormones that stimulate cell division, growth, and specialization. They are essential for processes such as the formation of shoots, the development of leaves, seed germination, and the prevention of leaf aging (senescence).
