Discover how plants interact with their environment through various growth movements known as tropisms. Learn about different types such as phototropism, where plants grow towards light, and solar tracking, which allows leaves and flowers to follow the sun. Explore thigmotropism, the response to solid objects that aids climbing, and gravitropism, where roots grow downward and stems upward in response to gravity. Additionally, uncover chemotropism, the response to chemicals, illustrating the remarkable adaptability of plants.

Do plants respond to their environment?
Plant Tropisms Growth movement toward or away from...
Tropisms are caused by growth hormones.
Phototropism a growth response to light Solar tracking is a hydroscopic movement of leaves or flowers as they follow the sun's movement across the sky.
Thigmotropism a growth response to contact with a solid object Thigmotropism allows vines to climb.
Gravitropism a growth response to gravity Roots are positively gravitropic, growing downward.
Gravitropism a growth response to gravity Stems are negatively gravitropic, growing upward.
Chemotropism a response to chemicals
