Science Revision

Particles
1. Particles make up different things depending on how closely packed they are.
  1. Solid - very closely packed in rows.
  2. Liquid - close together but with no arrangement.
  3. Gas - not at all close and moving fast
Cells
1. All living things are made from cells
2. Diagram
  1. Cytoplasm - where chemical reactions happen.
  2. Membrane - lets substances in and out of cell
  3. Nucleus - contains genes and controls cell
3. Some cells are specialised cells. This means that they have adapted to do a certain job.
  1. Nerve cell (neurone)
  2. Red Blood cell
  3. Sperm cell
  4. Egg cell (ovum)
  5. Ciliated Epithelial cell
  6. Rot Hair cell
