Question

factors influencing growth
ms - ls1 - 5

1. which is not a stimulus that can trigger tropisms in plants?

a. light
b. gravity
c. touch
d. temperature

Explanation:

Tropisms are directional growth responses of plants to external stimuli. Phototropism (response to light), gravitropism (response to gravity), and thigmotropism (response to touch) are well - known tropisms. While temperature can affect plant growth and development (e.g., in terms of metabolic rates), it does not trigger a directional growth response (tropism) in the same way as light, gravity, or touch.

Answer:

D. temperature
