Answer 1

Plant hormones are known asphytohormonesin botanical terms. They are chemicals just like animal hormones that help in the growth, development, and functioning of plants. Like animals, plants too are living organisms that function as a unit. They carry out vital biochemical reactions that are required to survive.

Answer 2

Plant hormones are chemicals in plants that regulate cellular processes. They are usually found in small amounts throughout the plant. These hormones are very important as they determine many different attributes of a plant. Plant hormones can be natural or synthetic.

Plant hormones are also known as phytohormones.

The five major plant hormones are auxins, gibberellins, cytokinins, abscisic acid, and ethylene. These hormones will work independently or together to influence plant growth and health.

Auxins and gibberellins help promote plant growth, particularly in stem elongation.

Cytokines promote cell division and are produced in growing areas of plants.

Abscisic acid plays a role in cell dormancy and is involved in the opening and closing of the stomata on leaves.

Finally, ethylene is a gas that is produced by ripening fruits.Ethylene is one particular hormone that is often synthetically produced so gardeners can purposefully ripen fruits of many plants at the same time.
