Geotropism is a type of tropism, which is the growth or turning movement of a biological organism in response to an external stimulus. In the case of geotropism, the stimulus is gravity. This phenomenon is commonly observed in plants, where the roots exhibit positive geotropism, growing downwards towards the center of the Earth, while the stems and shoots exhibit negative geotropism, growing upwards away from the Earth's center. This growth pattern is crucial for the plant's overall structure and function, as it allows the roots to access water and nutrients from the soil, while the shoots can reach for sunlight and grow towards the sky. Geotropism is a fundamental aspect of plant biology and plays a significant role in the development and survival of plant life.
