Resource summary

B2.1
  1. Cells And Specialised Cells
    1. Mitochondria; Provides energy for cell.
      1. Cytoplasm ; where all chemical reaction take place
        1. Vacuole; Contain cell sap, mentains plants shape
          1. Ribosomes; Where protein sythessis takes place
          2. Yeast And Bacteria Cells
            1. Bacteria Cell
              1. Flagellum (not always present)
                1. Plasmid DNA; comes in small loops and carried extra information
                  1. Chromosomal DNA; giant loop of DNA containing most genetic material.
                  2. Prokaryotic Cell; A cell without a nucleus ( bacterial cell )
                    1. Eukaryotic Cell; A cell with a nucleus ( yeast, animal etc.)
                    2. Diffusion
                      1. Diffusion Is Particles Moving From High Concentration To Low Concentration As They Spread Out
                        1. Happens when particles are free to move
                          1. This is true in gases and for particles dissolved in solutions.
                          2. Factors that effect rate of diffusion are surface are, concentration volume and temperature
                          3. Photosythessis
                            1. Process where plant makes their own food
                              1. During photosynthesis: Light energy is absorbed by chlorophyll, a green substance found in chloroplasts in some plant cells and algae Absorbed light energy is used to convert carbon dioxide (from the air) and water (from the soil) into a sugar called glucose Oxygen is released as a by-product
