Answer:

phototropism

Explanation:

Phototropism is the phenomenon that is causing the bean seedling to bend as shown.

Phototropism is known to be the growth of a plant or an organism in response to a light stimulus. This means that plants or organisms grow in the direction of the light. From the image shown, we will discover that the bean seedling is bending towards the direction of the sunlight.
