Question
Discuss briefly the hydrotropic movement in plants.
Answer
Hydrotropism is a type of tropism in which the roots of a plant grow towards a source of water. It is an important adaptive mechanism that allows plants to find and obtain water in their environment, which is essential for their survival and growth.
There are two main types of hydrotropic movements: positive hydrotropism, in which roots grow towards a source of water, and negative hydrotropism, in which roots grow away from water. Positive hydrotropism is the most common type of hydrotropism and is exhibited by most plants.
An example of positive hydrotropism can be seen in the roots of maize plants, which grow towards a source of water in the soil.
