Answers
PHOTOTAXIS is a behavior in animals where it move toward or away from a light source. PHOTOTAXIS is the movement of a motile organism towards or away from the light source according to the intensity of light. Movements directed toward or away from sources of light are further described respectively as positive or negative. An example of positive phototaxis is a moth's flight toward a shining lamp. The tendency of a ciliate cell to swim toward darker waters exhibits negative phototaxis.
Explanation:
Phototaxis signifies a kind of behaviour where animals start drifting away from the main It is a kind of taxis or locomotion where the entire body of the animal moves from one destiination to another. It occurs when the stimulus of light cannot be escaped by an organism and it gradually tries to move away from the main light source. This phenomenon is advantageous for the phototrophic organisms as they can orient themselves as per the direction and the source of light and they grow toward the light's direction.
