WebThe four plant hormones and their functions are as follows: 1) Auxin: It promotes cell enlargement and cell differentiation in plants. 2) Gibberelins: It breaks the dormancy in seeds and buds. 3) Cytokinins: It promotes cell division in plants. 4) Abscisic acid: It promotes closing of stomata. Concept: Co-ordination in Plant: Tropism in Plants WebImportant plant hormones include: auxins which control the rate of cell elongation gibberellins also control cell elongation but also influence germination, flowering and dropping fruit and...

Plant hormone - Wikipedia

WebThe hormones of plants Growth in plants is regulated by a variety of plant hormones, including auxins, gibberellins, cytokinins, and growth inhibitors, primarily abscisic acid … Like auxins, cytokinins are a group of related molecules that regulate growth and development. However, the plant’s response to cytokinin is very different from the responses to auxin. Cytokinin comes from the word cytokinesis, which means cell division. You will learn about cytokinesis, specifically mitosis, in … See more Auxins are a group of related molecules that are involved in almost every aspect of the plant’s life cycle. Auxins stimulate growth through cell elongation, which is integral to the plant’s responses to environmental … See more Gibberellins, or gibberellic acid (GA), are a group of over 100 molecules that are primary regulators of stem elongation and seed germination. They were discovered during research on the cause of the “foolish seedling” … See more Ethylene is well known as the gaseous, ripening hormone. It also regulates seedling growth and the formation of root hairs, and can lead to epinasty — the bending of branches downwards. Many plants are sensitive … See more While GA facilitates seed germination, abscisic acid (ABA) inhibits it. Abscisic acid is a single molecule that regulates germination and the response of a plant to reduced water … See more celeron® プロセッサー1000m

During winter or periods of drought, which one of the following plant hormones inhibits growth and seed germination? a. ethylene b. abscisic acid c. gibberellin d. auxin. WebGenerally, there are five types of plant hormones, namely, auxin, gibberellins (GAs), cytokinins, abscisic acid (ABA) and ethylene.
