Introduction of Plant Hormones
Plant hormones are chemicals that affect plant growth. There are three main types: auxins, gibberellins, and cytokinins. Auxins are responsible for promoting cell elongation, gibberellins for stem growth and flowering, and cytokinins for cell division.
MCQs on Plant Hormones
Plant hormones are chemicals that regulate plant growth. There are five major classes of plant hormones: auxins, gibberellins, cytokinins, abscisic acid, and brassinosteroids.
Auxins are the most important class of plant hormones. They are produced in the tips of the plant’s shoots and control the growth of the plant. Auxins promote cell division and elongation, and they are also responsible for the initiation of root growth.
Gibberellins are produced in the tips of the plant’s shoots and control the growth of the plant. Gibberellins promote cell division and elongation, and they are also responsible for the germination of seeds.
Cytokinins are produced in the tips of the plant’s shoots and control the growth of the plant. Cytokinins promote cell division and elongation, and they are also responsible for the differentiation of cells.
Abscisic acid is produced in the leaves and fruits of plants and controls the growth of the plant. Abscisic acid inhibits cell division and elongation, and it also promotes the production of seeds.
Brassinosteroids are produced in the leaves and fruits of plants and control the growth of the plant. Brassinosteroids promote cell division and elongation, and they are also responsible for the production of chlorophyll.
