Explanation:
The tropic movements in plants can be defined as growth movement in response to a specific stimulus such as light, gravity, temperature, chemical substances, water, solid particles. The plants can show either positive (towards the stimulus) or negative (away from the stimulus) growth movement in response to the particular stimulus.
The shoot of the plant bend towards the light when it is kept in a cardboard box with a small hole on one of its side, this happens due to phototropism.
Phototropism is a phenomenon in which the growth of the plants takes place in distant from the sunlight contain greater auxin concentration show faster growth, which eventually causes the shoot to bend towards the light that enters through the hole of the cardboard box. This mechanism enables plants to revamp the amount of light they receive to enhance the rate of photosynthesis.
hope it helps
