They are examples of organelles
Parts of the cell
Mitochondria and chloroplasts are thought to have once been a free prokaryotic cell.
No they do not. They are in chloroplasts.
There are three characteristics of mitochondria and chloroplasts that support this theory. First, both mitochondria and chloroplasts have two membranes surrounding them. Second, like prokaryotes, mitochondria and chloroplasts contain ribosomes, as well as a circular DNA molecules attached to their inner membranes. Third, mitochondria and chloroplasts are autonomous.
Mitochondria and chloroplasts have their own DNA. Mitochondria DNA is circular, similar to bacterial DNA, and is inherited maternally. Chloroplasts also have circular DNA and are thought to have originated from endosymbiotic relationships with ancient prokaryotes.
The Organelles
Parts of the cell
cytoplasmic organelles both of them have their own DNA
Examples of mitochondria include liver cells and muscle cells, which require a lot of energy and therefore have a high number of mitochondria. Examples of chloroplasts include leaf cells in plants, where photosynthesis occurs to convert sunlight into energy.
Mitochondria and Chloroplasts are involved in energy conversion.
