Plant hormones 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. These biochemical reactions require hormones also known as 'plant growth substances'. These hormones help in formation of leaves, flowers, stems, fruit, etc.
