Detailed explanation-1: -Like all organisms, plants detect and respond to stimuli in their environment. Unlike animals, plants can’t run, fly, or swim toward food or away from danger. They are usually rooted to the soil. Instead, a plant’s primary means of response is to change how it is growing.

Detailed explanation-2: -Plants respond to their environment in a variety of ways. 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-3: -Solution : Both plants and mammals respond to external stimuli. Animals show slow response to stimuli while plants show slow response to stimuli. Plants show response only to certain stimuli, generally light and touch.

Detailed explanation-4: -Because plants require sunshine to thrive, they will tilt or migrate towards the source of light. Phototropism is the name given to this type of movement. Negative phototropism occurs when a plant travels away from a light source.

Detailed explanation-5: -Behavior can also be thought of as a response to a stimulus-some change in the body or in the environment. All animals, even those too small to be seen without a microscope, respond to stimuli.
