Geotropism, also known as gravitropism, is the growth response of plants influenced by gravity. In roots, geotropism is positive, causing them to grow towards gravity, anchoring the plant in the soil. This aids in soil exploration and nutrient absorption. In shoots, geotropism is negative, with stems growing against gravity. This promotes upward growth towards light for optimal photosynthesis. The process involves the redistribution of auxin hormone, which moves towards the lower side in roots (stimulating growth) and the upper side in shoots (inhibiting growth). Geotropism enables plants to adapt their growth direction based on gravitational cues.
