Cells
  1. Animal
    1. 1) Nucleus; contains DNA
      1. 2) Cytoplasm; gel-like substance, chemical reactions occur
        1. 3) Cell membrane; holds cell together, controls what goes in & out
          1. 4) Mitochondria; where reactions for respiration take place {releases energy for the cell to work}
            1. Plant
            2. Plant
            3. Plant
          2. Plant
            1. 4) Ridged cell walls; supports cell, made of cellulose
              1. 5) Large Vacuole; contains cell sap
                1. 6) Chloroplasts; photosynthesis occurs, contains chlorophyll
            2. Bacteria
              1. 1) Chromosomal DNA; controls activities and replication, floats in cytoplasm
                1. 2) Plasmids; extra DNA (not part of chromosomes), contain genes
                  1. 3) Flagellium; rotates to make bactirium move, like a tail
                    1. 4) Cell Wall, supports cell
              2. Cells are studied using microscopes
                1. Light Microscopes; invented in the 1590s
                  1. Electron Microscopes; invented in the 1930s (let you see smaller things in more detail than light microscopes
                    1. Calculate magnification; length of image ---------------------------------- length of specimin
