Detailed explanation-1: -Hydrotropism is the movement or growth of a plant towards water. It is a type of tropism, or directional growth response, that is triggered by water. Plants are able to detect water through various stimuli, including changes in moisture levels and changes in water potential.
Detailed explanation-2: -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-3: -A positive hydrotropism is one in which the organism tends to grow towards moisture whereas a negative hydrotropism is when the organism grows away from it. An example of positive hydrotropism is the growth of plant roots towards higher relative humidity level.
