Gravitropism allows plants to respond to gravity, enabling them to grow their roots downward and their stems upward. This response helps plants anchor themselves in the soil and optimize their access to light and nutrients.
Phototropism allows plants to respond to light by growing towards it. This response helps plants maximize their exposure to sunlight, which is crucial for photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth and development.
