  • Cells
    • Specialised Cells
      • Plant Cells
        • Palisade Cells
          • They are found on the top of a leaf.
          • They have a large surface area to help absorb lots of water and sunlight.
          • They have lots of chloroplasts to absorb sunlight with.
        • Root hair cell
          • They are found in the root's hairs.
          • They have a large vacuole to store water.
          • They have thin cell walls to let water in easily.
        • Xylem
          • Xylem cells have a hollow inside to allow water to run through easily.
          • They also have round rings in them to help strengthen the cells walls.
          • They have a broken end wall so the water to come in and out.
      • Animal Cells
        • Sperm Cell
          • This cell has lots of mitochondria to power it along to the egg.
          • It has lysosomes to digest its way into the egg.
          • It has a tail to swim to the egg with.
          • It carries the fathers DNA to the egg.
        • Red Blood Cell
          • It has no nucleus to make room for haemoglobin and therefore more oxygen molecules.
          • It has a dip in the middle to carry oxygen molecules in.
    • Key Words
      • Nucleus
        • It controls the cell and contains DNA.
      • Mitochondria
        • This organelle releases energy when you breath out.
      • Cell Specialisation
        • When a cell is specially adapted to doing a certain job/function.
      • Diffusion
        • The movement of particles from a high concentration to a low concentration.
      • Ribosome
        • The cell structure that produces proteins.
    • More Key Words.
      • Cell Membrane.
        • This controls what goes in and out of the cell.
      • Cytoplasm.
        • The liquid inside the cell where most chemical reactions take place.  It suspends everything in the cell inside it.
      • Cell Wall.
        • It is only found in plant cells and keeps the cell supported and upright.
      • Chloroplasts.
        • These are only found in plant cells and are used to do photosynthesis.
      • Plasmid.
        • A circular strand of DNA found in bacteria cells.
      • Cells
        • The smallest functional unit of an organism.
      • Tissues
        • A group of similar cells working together to perform a function.
      • Organs
        • A group of tissues working together to perform a function.
      • Organ System
        • A group of organs working together to perform a function.
      • Eukaryotic cells
        • Cells that contain their genetic material in a nucleus.  Such as plant and animal cells.
      • Prokaryotic
        • Cells that don't have a nucleus and the DNA floats free in the cytoplasm.  Such as bacteria cells.
      • Genes
        • Section of DNA that contains the information for a characteristic
