Resource summary

Cells
  1. All cells contain:
    1. DNA
      1. In a double helix shape
        1. Contain the genetic code
        2. Organelles
          1. Helps the cell perform a specific function
        3. Animal cells
          1. cytoplasm
            1. Where chemical reactions take place
              1. Anaerobic respiration
                1. production of enzymes an proteins
              2. Mitochondria
                1. Where aerobic respiration takes place
                2. nucleus
                  1. Where the DNA and code for making enzymes and proteins within the cell are held
                  2. cell membrane
                    1. Allows water and certain gassesin and out but keeps other chemicals from passing through
                  3. Plant cells
                    1. Cell wall
                      1. strengthens cell
                      2. Permanent vacuole
                        1. Helps support the cell
                        2. chloroplasts
                          1. Contains the green pigment chlorophyll which helps absorb light energy
                            1. Contains some enzymes needed for photosynthesis
                          2. Microbial cells
                            1. Bacteria cells
                              1. Cytoplasm
                                1. contains enzymes for both aerobic and anaerobic respiration
                                2. Cell wall
                                  1. Supports cell: unlike plants cells it is not made of cellulose but instead of proteins
                                  2. Cell membrane
                                    1. Allows certain gasses and chemicals to enter and leave the cell freely and acts as a barrier to other chemicals and gasses
                                    2. DNA
                                      1. circular in shape and floats freely in the cytoplasm
