The innermost matrix of chloroplasts, called the stroma, contains metabolic enzymes and multiple copies of the chloroplast genome. Chloroplasts also have a third internal membrane called the thylakoid membrane, which is extensively folded and appears as stacks of flattened disks in electron micrographs.
A chloroplast is a type of plant cell organelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production. A chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.Hence, the name chloroplast indicates that these structures are chlorophyll containing plastids.Like mitochondria, chloroplasts have their own DNA, are responsible for energy production, and reproduce independently from the rest of the cell through a division process similar to bacterial binary fission. chloroplast contains a green pigment called chlorophyll, which absorbs light energy for photosynthesis.
