Question

Explain giving reasons the bending of the shoot tip of a plant towards light coming from side of the plant

Answer 1

Answer:

When the shoot tip of a plant bends towards the light, it is known as phototropism.

Explanation:

Phototropism is the response of a plant or particular organisms towards the light. The light acts as a stimulus for growth. The hormone present in the plants, namely auxin, facilitates the cells to grow longer as a response to the light. When the light falls on a plant, the auxin spread towards the shady area of the plants.

The phenomenon gives a curvature shape to the plant and hence, the shoot tip of the plant bends towards the light.

Answer 2

Answer: The reason for the bending of the shoot tip of a plant towards light source coming from one side of the plant is due to a phenomenon called as positive phototropism.
