      Plants have less groups of hormones than animals and humans. Plant hormones usually affect many, or most, of the cells of the plant. They are not organised in glands like animal/human hormones as they are generally released from cells themselves and either work locally or travel in the plant’s transport system. Hormone responses in plants are slower than the the response in animals/humans.

      Auxin is a plant hormone that is released from the growing tip of the plant and stimulates growth. Gibberellins trigger cell elongation and divisions as well as overall plant growth.

      Animals and humans are a lot more complex. They have numerous hormones which are released from glands and can travel through the body in the bloodstream to work on distant cells and tissues.
