Question

What kind of movement is seen in the roots of plants

Answer 1

Answer:

Roots always move in downward direction towards the gravity of the earth, this type of movement is called geotropism. The word "geo" means earth and "tropism" mean movement in a certain direction.

Roots also move towards water in the soil, this type of movement is known as hydrotropism.

There are many sensors that are present in the tips of the roots which detect the presence of water and move the root toward that direction.
