PHYTOHORMONES Meaning and
Definition
-
Phytohormones, also known as plant hormones or plant growth regulators, are naturally occurring organic substances that regulate various aspects of plant growth and development. These hormones play crucial roles in controlling plant growth processes such as cell division, elongation, differentiation, and differentiation of tissues. Phytohormones are produced in specific tissues or organs of plants and are transported to other areas where they elicit specific responses.
There are five major classes of phytohormones: auxins, gibberellins, cytokinins, abscisic acid, and ethylene. Auxins are responsible for promoting cell elongation, lateral root formation, and apical dominance, while gibberellins stimulate stem elongation and seed germination. Cytokinins regulate cell division and differentiation and are involved in the promotion of shoot and root growth. Abscisic acid regulates seed dormancy, stomatal closure, and stress responses, while ethylene is involved in various processes such as fruit ripening, leaf senescence, and stress responses.
Phytohormones act by binding to specific receptor proteins in target cells, starting a series of signaling events that ultimately lead to physiological responses. The concentration and distribution of these hormones within a plant are tightly regulated, and their effects can be influenced by environmental factors such as light, temperature, and stress. The precise balance and interaction between these different hormones determine various aspects of plant growth and development, including seed germination, root and shoot growth, flowering, fruit development, and senescence.

Etymology of PHYTOHORMONES
The word "phytohormones" comes from the Greek roots "phyto-" meaning "plant" or "plant-related", and "hormone", which also has Greek origins meaning "to set in motion" or "to excite". Thus, "phytohormones" can be understood as "plant hormones", referring to the chemical substances that regulate various physiological processes in plants, such as growth, development, and response to environmental stimuli.
