Plant Hormone | B.Sc. Botany 5th Semester | Paper-1st | Unit-5 | NEP-2020

Plant hormones, also known as phytohormones, are chemical substances produced by plants that regulate various physiological processes, such as growth, development, and responses to environmental stimuli. They are essential for coordinating the growth and functioning of plants. The five major classes of plant hormones are: Auxins Definition: Auxins are a class of plant hormones that regulate growth, especially elongation and differentiation of plant cells. Functions: Promote cell elongation in stems and roots. Inhibit the growth of lateral buds (apical dominance). Involved in phototropism (growth towards light) and gravitropism (response to gravity). Stimulate the formation of adventitious roots. Help in fruit development and growth. Examples: Indole-3-acetic acid (IAA), Indole-3-butyric acid (IBA), and Naphthalene acetic acid (NAA). Synergistic Interactions: In some cases, plant hormones work together to produce a combined effect. For example, cytokinins and auxins often cooperate to promote cell division and differentiation. Antagonistic Interactions: Some hormones act in opposition to each other, such as the relationship between auxins and cytokinins, where high levels of auxins inhibit bud formation, while high levels of cytokinins promote it. #bscbotany #bscbotany #physics #science #zoology Join this channel to get access to perks:    / @letsstudyindia   ======================================== Thank-You For Watching This Video...!!
