6.2 page 98-101 Eukaryotic cells have internal membranes that classify their functions  I. There are two types of cells: eukaryotic (protists, fungi, animal, plants) and prokaryotic  (bacteria,  archaea)  II. All cells are bounded by a plasma membrane  - Inside the  plasma   membrane  is a fluid called  cytosol  in which organelles are found Chromosomes  carry genes in the form of DNA Ribosomes  are tiny organelles that make proteins - Inside a prokaryotic cell, the DNA is concentrated in a region called the  nuceloid   III. Eukaryotic Cells - Inside a eukaryotic cell, the region between the nucleus and the plasma membrane is called the  cytoplasm - As an object increases in size, its volume grows proportionately more than its surface area; the  smaller the objet he greater its ration of surface area to volume Microvilli  increases surface area without an appreciable increase in volume  - The cell’s compartments provide different local environments that facilitate specific metabolic  functions, so incompatible processes can go on simultaneously inside the same cell Page 100-101 describes the parts of the animal and plant cell
