Question

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.

Answer 1

An example of growth-dependent plant movement is a phototropic movement of plant shoot towards the sunlight. When a growing plant is exposed to light from only one side, then it responds by bending its stem (or shoot) towards the light.
This is an example of phototropism.
