Describe the structure of a chloroplast. How do the inner membranes differ from the outer membrane?

Chloroplasts are organelles present in plant cells and some eukaryotic organisms. Chloroplasts are the most important plastids found in plant cells. It is the structure in a green plant cell in which photosynthesis occurs.

Chloroplast is one of the three types of plastids. The chloro plasts take part in the process of photosynthesis and it is of great biological importance. Animal cells do not have chloroplasts. All green plant take part in the process of photosynthesis which converts energy into sugars and the byproduct of the process is oxygen that all animals breathe. This process happens in chloroplasts.

The distri bution of chloroplasts is homogeneous in the cytoplasm of the cells and in certain cells chloroplasts become concent rated around the nucleus or just beneath the plasma membrane. A typical plant cell might contain about 50 chloroplasts per cell.
