What is hydrotropism?

Hydrotropism is a plant's growth response in which the direction of growth determined by a stimulus or gradient in water concentration.

Design and experiment to demonstrate hydrotropism

Activity to show hydrotropism:

1. Soak the seeds in water overnight.

2. Place moist cotton in a perforated petri dish.

3. Put the soaked seeds in the petri dish & place it on a beaker.

4. Roots pass through pores and grow downwards.

5. After sometime roots will bend towards base of petri dish having moisture.
