name and explain the different types of plant hormones
Answers
Answer:
Hormones get things done. Think of them as chemical messengers that are made in one place in the body and deliver their message in a totally different place in the body. And just like hot sauce, a little goes a long way. Hormones are usually found in very small concentrations, but boy to they pack a punch! We know hormones cause a lot of changes in humans (ah, puberty), but did you know that plants have hormones, too? Plants miss out on all the fun of body hair, acne, and voice changes, but read on to learn about the amazing effects that hormones have on plant growth and development!
Answer:five major types of plant hormones: auxin, gibberellin, cytokinin, ethylene, and abscisic acid. These hormones can work together or independently to influence plant growth.
Explanation:
AUXIN
Auxin is involved in cell growth and cell expansion, so it is produced primarily in parts of the plant that are actively growing like the stem.
GIBBERELLIN
Gibberellins play an important role in several developmental stages in plants, but their claim to fame is making stems longer. Gibberellins promote stem elongation between nodes on the stem.
CYTOKININ
Cytokinins are involved in repair, too. If a plant becomes wounded, it can fix itself with the help of cytokinins and auxin.
ETYLENE
Ethylene is a plant hormone that affects ripening and rotting in plants. It is a particularly interesting plant hormone because it exists as a gas. No other plant hormone is gaseous! Ethylene can be produced in almost any part of a plant, and can diffuse through the plant’s tissue, outside the plant, and travel through the air to affect a totally different plant.
