Growth movements in plants


The kind of plant movement which occurs due to unequal growth on two sides of plant organ like stem, roots, tendrils, buds etc., is known as growth movement. These are three general types of growth movements.

  • Epinasty
  • Hyponasty
  • Nutation

(i) Epinasty: The growth movement in which upper side or surface of leaf shows more growth as compared with the lower surface is called epinasty.

(ii) Hyponasty: If growth in the lower surface of the leaf in bud condition is more than that the upper surface then the bud will remain closed.

(iii) Nutation: Zigzag movement of growing tip of young stem due to alternate change in growth on opposite side of the apex is termed as nutation.
