Biology: Cell Structure

1. Identifying cells

   • An animal cell is made up of three basic things
     • Nucleus
       • This acts as the brain of the cell
     • Cytoplasm
       • This is where chemical reactions take place
     • Cell Membrane
       • This controls what enters and leaves the cell
   • A plant cell is made up of six basic things
     • Nucleus
     • Cytoplasm
     • Cell Membrane
     • Cell wall
       • This keeps the cell rigid
     • Chloroplasts
       • This is where the plant keeps its food
     • Central Vacule
       • This is where the sap is kept
   • Cell Ultrastructure
     • Mitochondrion
       • This creates energy for ther cell
     • Ribosome
       • This is where ATP is made

2. Different Cell Types

   • Eukaryote Cells
     • These cells have a true nucleus
     • These cells make up organelles
   • Prokaryote Cells
     • Have nuclear material but not a true nucleus
     • They do not make up organelles but often stay ithin them to survive
     • They have additional DNA called a plasmid
