Describe the importance of surface area to volume ratios in cells. Concept 6.2: Eukaryotic cells have internal membranes that compartmentalize their functions •The basic structural and functional unit of every organism is one of two types of cells: prokaryotic or eukaryotic •Only organisms of the domains Bacteria and On the sketch of a prokaryotic cell, label each of these features: bacterial chromosome, nucleoid, cytoplasm, flagella.
