Detailed explanation-1: -An example of positive hydrotropism is the growth of plant roots towards a higher humidity levels where the plant can sense this at the root cap and it will then send a signal to the elongating part of the root.

Detailed explanation-2: -•The movement of a plant part in response to water is called hydrotropism. •For example, the roots of the plant show its movement towards water availability. • This is an example of positive hydrotropism.

Detailed explanation-3: -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-4: -Hydrotropism is a plant’s response to a stimulus or gradient in water concentration that determines the direction of growth. As they move and grow towards the water, roots exhibit a positive hydrotropic response.
