Answer: Positive phototaxis

Explanation:

Taxis is defined as the movement of organism under a stimulus. The stimulus can be light, food etc. Phototaxis is the movement of an organism when the stimulus is light. (Photo + taxis = light + taxis).Taxis is one of the many innate behavioural responses. There is a difference between tropism and taxis as tropism simply refers to a growth towards/away from the stimulus for e.g phototropism is shown by plants by growing towards the direction of sunlight. However, taxis is not growth but the movement towards/away from the stimulus .Phototaxis that is the movement when the stimulus is light is of two types:

1. Positive phototaxis - when an object move towards light. E.g euglena.

2. Negative phototaxis- when an object moves away from light. This is seen in insects such as cockroaches.
