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: -The survival of terrestrial plants depends upon the capacity of roots to obtain water and nutrients from the soil. Directed growth of roots in relation to a gradient in moisture is called hydrotropism and begins in the root cap with the sensing of the moisture gradient.

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: -Movement in response to water. Movement of plants in response to water or moisture is called hydrotropism. Here, water is a stimulus to which the plant can show two responses: i) It can move towards the water source-positive hydrotropism. ii) It can move away from water source-negative hydrotropism.
