Detailed explanation-1: -Hydrotropism is a plant’s response to a stimulus or gradient in water concentration that determines the direction of growth. Roots exhibit a positive hydrotropic response as they move and grow towards the water.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Background and Aims. Root hydrotropism is a response to water-potential gradients that makes roots bend towards areas of higher water potential. The gene MIZU-KUSSEI1 (MIZ1) that is essential for hydrotropism in Arabidopsis roots has previously been identified.

Detailed explanation-5: -Hydrotropism refers to the tropic movement in plants that occurs in response to the unidirectional stimulus of water. This directional growth movement of curvature is generally exhibited by roots, which are said to be positively hydrotropic (roots bend towards the water source).
