The outer layer of the double membrane is much more permeable than the inner layer, which features a number of embedded membrane transport proteins. Enclosed by the chloroplast membrane is the stroma, a semi-fluid material that contains dissolved enzymes and comprises most of the chloroplast's volume. Since, like mitochondria, chloroplasts possess their own genomes (DNA), the stroma contains chloroplast DNA and special ribosomes and RNAs as well.
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.t is the structure in a green plant cell in which photosynthesis occurs. Chloroplast is one of the three types of plastids.
