Question

Thigmotropism is best exhibited by

• A. Tendrils
• B. Stem apex
• C. Root apex
• D. Leaf apex

Answer 1

The correct option is A Tendrils

Thigmotropism is the directed tropical growth movement of plant in response to touch. Tendrils are the modified leaves that grow straight until it touch the support. Contact with any support stimulates the cell to grow at different rates at opposite sides of tendrils and causes their curling around the support. Thus, option A is correct.
