The chloroplast is an organelle found in plant cells and some protists. Its primary function is photosynthesis, the process of converting light energy into chemical energy.Functions of the Chloroplast:Photosynthèsis – Converts sunlight, carbon dioxide, and water into glucose (food) and oxygen.Energy Production – Produces ATP and NADPH in the light-dependent reactions.Carbon Fixation – Uses the Calvin cycle to convert CO₂ into organic molecules.Storage of Starch – Stores excess glucose in the form of starch.Synthesis of Pigments & Fàtty Acids – Produces chlorophyll and other pigments essential for photosynthesis.Oxygen Release – Releases O₂ as a byproduct of photosynthèsis, essential for life on Earth.
