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

Detailed explanation-2: -One of the lesser-known tropisms is hydrotropism, directed growth in response to water or moisture gradients.

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.
