• Plasma membrane - Phospholipid bilayer that separates the cell from its environment Allows passage of oxygen, nutrients, wastes
• Cytosol - A semifluid substance where organelles are suspended
• Cytoplasm - region between plasma membrane and nucleus
• DNA - Chromosomes contain genetic material in the form the required.
• Ribosomes - Tiny organelles that make proteins using instructions contained in the genes
• Prokaryotes -

  Bacteria, Archaea

  Nucleoid, no membrane bound nucleus

  Circular strand of DNA

  Few organelles
• Eukaryotes -

  Protists, Fungi, Plants, Animals

  Nucleus bound by a membrane
