Question

Growth of a Plant in response to a light stimulus is known as

• A. Geotropism
• B. Hydrotropism
• C. Phototropism
• D. None of the above

Answer 1

The Correct Option is C

To solve the problem, we need to identify the term used to describe the growth of a plant in response to a light stimulus.

1. Understanding Tropisms:
Plants respond to external stimuli with growth movements called tropisms:

• Geotropism: Response to gravity.
• Hydrotropism: Response to water.
• Phototropism: Response to light.

2. Confirming the Correct Answer:
The growth of a plant in response to a light stimulus specifically describes phototropism. Plants usually bend towards the source of light, demonstrating positive phototropism.

Final Answer:
The correct term is Phototropism (Option C).
