1. Go to Section: The Cell Theory  All living things are composed of cells.  Cells are the basic units of structure and function in living things.  New cells are produced from existing cells.

2. Go to Section: Prokaryotic Cells  Bacteria and cyanobacteria  No true nucleus; lacks nuclear envelope  Genetic material in nucleoid region  No membrane-bound organelles

3. Go to Section: Eukaryotic Cells  Plants, animals, fungi, protists  True nucleus; bounded by nuclear envelope  Genetic material within nucleus  Contains cytoplasm with cytosol and membrane-bound organelles
