What is Coordination in Plants?

 

Coordination is the ability to use different parts of the plant together, smoothly, and efficiently. In plants, coordination is due to the result of a chemical system, wherein plant hormones or phytohormones have a major role.

 

Plants exhibit two types of movements.

1. Growth-dependent movements called the Tropic Movements (towards or away from a stimulus).
2. Non-growth dependent movements called the Nastic Movements (independent of stimulus).

 

These can be classified again into 5 types. They are:

  • Phototropism (light)
  • Geotropism (gravity)
  • Hydrotropism (water)
  • Chemotropism (chemicals)
  • Thigmotropism (touch)

 

1. Phototropism – It is the movement of plants in response to light. The shoot system of a plant exhibits this characteristic. The shoot moves towards the light.

2. Geotropism – It is the movement of a plant part towards the soil. This is a characteristic of the root system. The roots always move in the direction of the earth’s gravity.

3. Hydrotropism– It is the movement of a plant towards the water. The stimulus here is water.

4. Chemotropism – It is the movement of plants in response to a chemical stimulus. A classic example of this type of movement is the growth of the pollen tube towards the ovule, during fertilization, in a flower.

5. Thigmotropism – It is a directional movement in plants in response to touch. For e.g. the plant tendrils climb around any support which they touch.
