Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis. Chloroplasts are one of the many unique organelles in the body, and are generally considered to have originated as endosymbiotic cyanobacteria.
Plant chloroplasts are commonly found in guard cells located in plant leaves. 1  Guard cells surround tiny pores called stomata, opening and closing them to allow for gas exchange required for photosynthesis. Chloroplasts and other plastids develop from cells called proplastids. Proplastids are immature, undifferentiated cells that develop into different types of plastids. A proplastid that develops into a chloroplast, only does so in the presence of light. Chloroplasts contain several different structures, each having specialized functions. Chloroplast structures include: Membrane Envelope - contains inner and outer lipid bilayer membranes that act as protective coverings and keep chloroplast structures enclosed.
