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 an organelle unique to plant cells that contains chlorophyll (which is what makes plants green) and is responsible for enabling photosynthesis to occur, so that plants can convert sunlight into chemical energy. chloroplast is a basic organelle that in a sense is one of the most important organelles to us, and we don't even have them!! In this lesson, we will be looking where chloroplasts are found and what their role and function is in cells.
