Question
What is geotropic movement?
Answer
A directional movement of a plant part in response to gravity is called geotropic movement.
- Example: Roots exhibit positive geotropism, meaning they grow downwards towards the ground. This helps them to anchor themselves in the soil and absorb water and nutrients.
- Example: Stems exhibit negative geotropism, meaning they grow upwards away from the ground. This helps them to reach for sunlight and carry out photosynthesis.
