  • Plant hormones are not nutrients, but chemicals that in small amounts promote and influence the growth, development, and differentiation of cells and tissues. (wikipedia.org)
  • The biosynthesis of plant hormones within plant tissues is often diffuse and not always localized. (wikipedia.org)
  • Plants lack glands to produce and store hormones, because, unlike animals-which have two circulatory systems (lymphatic and cardiovascular) powered by a heart that moves fluids around the body-plants use more passive means to move chemicals around their bodies. (wikipedia.org)
