Plant Hormone
Plant hormones are chemicals that regulate plant growth. There are five major classes of plant hormones: auxins, cytokinins, gibberellins, abscisic acid, and brassinosteroids. Each class of hormones has a unique function. Auxins stimulate cell elongation, cytokinins stimulate cell division, gibberellins stimulate stem growth, abscisic acid inhibits growth, and brassinosteroids activate gene expression.
Auxins and Gibberellins
Auxins are a group of plant hormones that stimulate cell division, elongation, and rooting. Gibberellins are a group of plant hormones that stimulate stem growth, seed germination, and flowering.
Auxins Definition
Auxins are a type of plant hormone that helps regulate plant growth. They are produced in the tips of young shoots and roots, and help control the rate of cell division and the direction of growth. Auxins also help plants respond to stimuli such as light and gravity.
Gibberellins Definition
Gibberellins are a family of plant hormones that are responsible for the elongation of stems and the breaking of dormancy in seeds. They are produced in the roots and leaves of plants, and are responsible for the growth of new cells. Gibberellins are also responsible for the production of enzymes that break down starch into glucose, which is the plant’s primary source of energy.
Difference between Auxin and Gibberellin
Auxin and Gibberellin are two types of plant hormones that are responsible for various functions in plants. Auxin is responsible for elongation of the plant, while Gibberellin is responsible for germination and seedling growth. Auxin is also responsible for root initiation and the development of lateral buds. Gibberellin is also responsible for breaking dormancy in seeds and promoting flowering.
Difference between Auxin and Cytokinin
Auxin and cytokinin are two types of plant hormones that regulate different aspects of plant growth and development. Auxin is responsible for regulating cell elongation, while cytokinin promotes cell division. Auxin also regulates the production of secondary metabolites, while cytokinin influences the growth of roots and shoots.
