How do plant grows towards light?
Asked by shudhanshujn | 28 Aug, 2014, 09:45: PM
Expert Answer
The tendency of the growth of the plant is termed as phototropism. The hormone responsible for photropism is auxin.Unequal auxin distribution is involved and transported away from the lighted side toward the darker side of the shoot. Since auxin stimulates cell elongation in shoots, this produces unequal growth on the two sides of the shoot and the shoot bends toward the light.
