The document provides an overview of photosynthesis, including: - Photosynthesis uses energy from sunlight to convert carbon dioxide and water into sugars and oxygen through a two-stage process of light-dependent and light-independent reactions. - Plants capture sunlight using pigments like chlorophyll located in chloroplasts. Light-dependent reactions in the chloroplast membranes use sunlight to produce ATP and NADPH to power the light-independent reactions. - The light-independent reactions use ATP and NADPH to produce sugars from carbon dioxide in the chloroplasts.
