Which of the following best describes geotropism?

Geotropism refers specifically to a plant's directional growth in response to gravity. This biological phenomenon enables plants to orient their growth appropriately in relation to gravitational forces, allowing roots to grow downward into the soil (positive geotropism) and shoots to grow upward toward the light (negative geotropism). This adaptation is crucial for survival, as it ensures that roots can access water and minerals while shoots can access sunlight for photosynthesis. Other types of tropisms, such as phototropism (growth toward light), hydrotropism (growth toward moisture), and thigmotropism (growth in response to touch), involve different stimuli and are distinct from geotropism.
