NEET BIOLOGY

Detailed explanation-1: -The response of an organism, usually a plant, to an environmental stimulus is called a tropism. Some common plant stimuli include light, gravity, water, movement of the sun, and touch. The naming of the tropism is associated with the stimulus.

Detailed explanation-2: -Summary. Like all organisms, plants detect and respond to stimuli in their environment. Their main response is to change how they grow.

Detailed explanation-3: -Plants respond to touch, light and heat.

Detailed explanation-4: -To survive and to thrive, plants rely on their ability to sense multiple environmental signals, such as gravity or light, and respond to them by growing and changing their shape. To do so, the signals must be transduced down to the cellular level to create the physical deformations leading to shape changes.
