response to water: hydrotropism, response to light: phototropism, response to chemicals: chemotropism, response to gravity: geotropism, response to touch: thigmatropism

Light intensity and the rate of photosynthesis relate to the position of the sun in a few ways. The higher the sun the faster the rate of photosynthesis.
Phototropism is the response to light. Geotropism is the response to gravity. Chemotropism is the response to particular substances. Hydrotropism is the response to water. Thigmotropism is the response to mechanical stimulation. Traumatotropism is the response to wound lesion. Galvanotropism is the response to electric current.

Yes the eye-spots have photoreceptors used to avoid light.
Planarians have eyespots which help them to sense light. They cant see any clear object but they can tell what is light or dark. Tapeworms dont see anything because they live inside our bodies and its dark so they dont need to see anything.
Planarians exhibit a fairly strong negative geo-tropism and would move away from light.
A positive tropic response is when an organism moves or grows towards a stimulus, such as light or nutrients. This type of response helps the organism to find resources or suitable conditions for survival and growth.
you can make them freak out by touching them. they start swimming in a different direction and sometimes run into things because they can only see light not details.
Response. The stimulus is the light.

The red light reflex (startle response) is a withdrawal response in the abdominal muscles in which the body curves in on itself in response to distress.
