Frontier Science on Instagram: "Let me explain the science… In negative gravitropism, plant shoots (like stems and leaves) grow upward and away from gravity to reach sunlight which is critical for photosynthesis. This mechanism involves specialized cells called statocytes which contain a special kind of starch called statoliths. These statoliths sense gravity and signalal to the plant which direction is “down”. In response, hormones such as auxin redistribute themselves, promoting growth on the
