Chloroplast structure. Artwork showing the internal structure of chloroplasts,the organelles in plant cells responsible for photosynthesis. The inner and outer lipid-bilayer membranes enclose the granum (stack of thylakoids,green layered objects),the plastidial DNA (white loops),ribosomes (yellow),and starch grains (blue-white). The ribosome at centre left is engaged in RNA translation and protein formation. It is the thylakoid stacks that are the site of photosynthesis,the capturing of energy from sunlight using the green pigment chlorophyll. This energy can be stored in the form of starch for later use | |
