What is tropism?

Tropism is the growth or movement of a plant in response to a stimulus, such as light, gravity, or touch. This response is typically directional, causing the plant to grow or move towards or away from the stimulus. Tropisms are important for plants to adapt to their environment and optimize their growth and survival. Some common types of tropisms include phototropism (response to light), gravitropism (response to gravity), and thigmotropism (response to touch).
