Question

What is hydrotropism? Describe an activity to demonstrate hydrotropism.

Answer 1

In plant biology, hydrotropism is a plant’s growth response toward water sources. Hydrotropism, which is triggered by plant hormones, can be a positive or negative response, whereby the plant will either turn away from water concentrations, protecting itself from oversaturation or move towards them, protecting itself in times of drought.

Activity to demonstrate hydrotropism:

Take a plant (pea seedling) in a nude jar filled with sand. Now place a porous pet filled with water in the wide jar. Roots of the plant will green towards water and bond towards the water source showing hydrotropism.
