What is a tropism?

Tropism is how a plant reacts to sunlight and water and also evan gravity.

A example is when a plant start growing in the direction of the sun.

Geotropism

The growth of a living organism that reacts to gravity, as the downward growth of plant roots!!!!!!

Plants that grow on hillsides are great examples of geotropism. They may start out growing on the side of the hill, but will eventually start to grow away from gravity and up toward the sunlight.
