HORTICULTURE

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: -Hydrotropism modifies root growth to respond to a water potential gradient in soil and grow towards areas with a higher moisture content.

Detailed explanation-4: -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-5: -Answer and Explanation: Geotropism is the growth of plant roots downward and is the effect that gravity has on a plant organism during its growth.
