What causes plants to grow towards the light?

Fungi
Photosynthesis
Gravity
Tropism

The correct answer is: Tropism

Tropism is the response of a plant to external stimuli, such as light. This is an important biological process that allows plants to maximize their exposure to sunlight for photosynthesis. Fungi do not play a role in the directional growth of plants towards light. While photosynthesis is the overall process that provides energy for plants to grow, it is not the specific cause of plants growing towards light. Gravity is another important factor in plant growth, but it does not influence the direction of light growth. Therefore, the correct answer is D Tropism.
