Question

venus flytraps are carnivorous plants that trap insects when they crawl along small hair - like triggers on the surface of the plant’s leaves. the disturbance of these hairs generates electrical signals within the plant that close the leaves and trap the insect in seconds. what is this response of the venus flytrap known as? select one:
○ a. phototropism
○ b. gravitropism
○ c. hydrotropism
○ d. thigmotropism

Explanation:

• Phototropism is a plant's response to light.
• Gravitropism is a plant's response to gravity.
• Hydrotropism is a plant's response to water.
• Thigmotropism is a plant's directional growth or movement in response to touch or physical contact, which matches the Venus flytrap's response to insect contact with its trigger hairs.

Answer:

d. Thigmotropism
