Question

What are two ways in which plant hormones control plant growth?

Answer 1

Plant hormones shape the plant, affecting seed growth, time of flowering, the s*x of flowers, senescence of leaves and fruits. They affect which tissues grow upward and which grow downward, leaf formation and stem growth, fruit development and ripening, plant longevity and even plant death. Hormones are vital to plant growth and, if they were to lack them, plants would be mostly a mass of undifferentiated cells.
