Plant parts show two types of movements, one dependent on growth and the other independent of growth.

Give one example of the movement in plant parts:


(a) which depends on growth


(b) which does not depend on growth

(a) Phototropism is the growth of plant parts in the direction of its light source. The bending of stem or shoot towards light shows this process.

(b) Touch me not (also known is Chui-mui) is a touch sensitive plant. When we touch the leaves of this plant then they get folded.
