thigmo is the ability of a plant to coil around the objects they touch.
Thigmo means touch.
Phototropism is the response of plants to light, gravitropism is the response to gravity, thigmotropism is the response to touch, and chemotropism is the response to chemical stimuli. Each tropism helps plants adapt to their environment and grow towards essential resources.
Tropism is a biological phenomenon where an organism responds to the stimulus brought by the environmental factors. Some examples include: chemotropism, heliotropism, phototropism, thermotropism and electrotropism.
