Mitochondria. A mitochondrion (mitochondria, plural), is a membrane-enclosed organelle that is found in most eukaryotic cells.Mitochondria are called the "power plants" of the cell because they are the sites of cellular respiration, where they use energy from organic compounds to make ATP (adenosine triphosphate). ATP is the cell's energy source that …Typically, the nucleus is the most prominent organelle in a cell. The nucleus (plural = nuclei) houses the cell’s DNA in the form of chromatin and directs the synthesis of ribosomes and proteins. Let us look at it in more detail ( Figure 3.11 ).
