- - - - All living things are made of cells
      - Eukaryotic cells are complex
      - Prokaryotic cells are simple and smaller
    - - Eukaryotes
        
        Cell membrane
        
        Controls what goes in and out of the cell
        
        Nucleus
        
        Contains genetic material
        
        Mitochondria
        
        Where aerobic respiration takes place
        
        Ribosomes
        
        Protein synthesis
        
        Cytoplasm
        
        Where chemical reactions occur
        
        Plant cells
        
        Cell wall
        
        Rigid, made of cellulose to support cell
        
        Permanent vacuole
        
        Contains cell sap, weak sugar solution
        
        Chloroplasts
        
        Contains chlorophyll, where photosynthesis occurs
      - Bacteria
        
        DNA strands
        
        Plasmids
        
        Cell wall
        
        Cell membrane
        
        Cytoplasm
        
        No chloroplasts or mitochondria
    - - Sperm
        
        Reproduction
        
        Enzymes for egg cell membrane
        
        Many mitochondria for energy
        
        Long tail and streamlined head
      - Nerve Cells
        
        Branched connections
        
        Carry electrical signals
        
        Ends to connect to nervous system
        
        Long
      - Root Hair
        
        Hairs
        
        Large surface area
        
        To absorb water and minerals
      - Muscle cells
        
        Long so have space to contract
        
        Lots of mitochondria for energy for contraction
      - Phloem and Xylem
        
        Joined end to end
        
        Tubes to transport food and water
        
        Xylem hollow to allow more to flow
        
        Phloem have few subcellular structures for more flow
