📚 Topic Summary
Photosynthesis is the process plants use to convert light energy into chemical energy in the form of sugars. This process occurs in the chloroplasts, which contain chlorophyll, the pigment that captures sunlight. Plants take in carbon dioxide from the air and water from the soil, and using sunlight, they produce glucose (sugar) and oxygen. The oxygen is released back into the atmosphere, while the glucose is used by the plant as food. Understanding photosynthesis is key to understanding how plants sustain themselves and how they contribute to the Earth's ecosystem.
