HORTICULTURE

Detailed explanation-1: -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-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.

Detailed explanation-3: -Root hydrotropism is a response to water-potential gradients that makes roots bend towards areas of higher water potential.

Detailed explanation-4: -One of the lesser-known tropisms is hydrotropism, directed growth in response to water or moisture gradients.

Detailed explanation-5: -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.
