Would a light source be considered an internal or external stimulus?

Answers

Answer 1
External stimulus because Plants may respond to the following external stimuli: Light: Plants rely on photosynthesis to convert light energy into chemical energy. Plants often grow towards a light source. This behavioral response is called positive phototropism.
Answer 2

For plants, light is an external stimulant. Phototropism is a response to light that plants have. The plant responds by orienting its growth in the direction of the light.

What is stimulus?

A stimulus is an occasion or any change in the environment that causes an organ or tissue to have a certain functional response.

An external or internal trigger is possible. Sensitive to external stimuli like sound and touch are sense organs like the ear and sensory receptors like those in the skin.

Direct one-to-one stimulus-response reactions are the most basic sort of response. The stimulus is a change in the environment, and the response is how the organism responds to it.

A stimulation that comes from outside the organism is known as an external stimulus. Light is one example of an outside stimulation. Although it comes from outside the body, it has an impact there as well.

Thus, it can be concluded that light is an external stimulus.
