The movement of a part of the plant towards gravity is called geotropism. Growth of roots of plants in downward direction is an example of geotropism. The movementof a part of the plant towards water is called hydrotropism, e.g., movement of roots.
The following are the type of plant movement in growth of roots:
Tropic Movements or Tropism. The movement of a plant in the direction of stimulus is known as tropic movement or tropism.
Types of Tropism. Tropic movements are of four types. These are:
Phototropism. The movement of a part of the plant towards light is called phototropism.

In plants two types of movements take place:
1. Tropic movements and
2. Nastic movements
Phototropism
The movement of a part of the plant towards light is called phototropism. Growth of aerial parts of a plant towards light is an example of phototropism.
2. Geotropism
The movement of a part of the plant towards gravity is called geotropism. Growth of roots of plants in downward direction is an example of geotropism.
3. Hydrotropism
The movement of a part of the plant towards water is called hydrotropism, e.g., movement of roots.
4. Chemotropism
The movement of a part of the plant towards a chemical is called chemotropism.During the process of fertilization the movement of pollen tube towards ovule due to secretion of a sugary chemical in the ovary is an example of chemotropism.
Nastic Movements
These are nondirectional movements which takes place neither towards nor away from the stimulus. The best example of nastic movement is folding and drooping of leaves of ‘touch me not’ plant when its leaves are touched with fingers.
