Detailed explanation-1: -Hydrotropism. The movement or the growth of a plant in relation to the stimulus of water is called hydrotropic movements and the equivalent response to the stimulus of water is called hydrotropism. In this type of movement, roots show the positive hydrotropic response, as they move and grow towards the water.

Detailed explanation-2: -The movement of a plant in response to the concentration of water is known as hydrotropism.

Detailed explanation-3: -1. Movement of plants in response to water is called hydrotropism. In this case, water is a stimulus to which the plant can show two responses. 2. It can move towards the water source-Positive hydrotropism.

Detailed explanation-4: -Whereas geotropic movement is a movement in response to the gravitational force of earth. Hydrotropism is movement in response to moisture. Phototropism is the movement in response to light.
