Under the five kingdom system cells can be
divided into two basic types.
Prokaryotic cells - simple cells without
distinct membrane bound organelles or nucleus.
Eukaryotic cells - more complex with
membrane bound organelles and nucleus.

  1. 1. Cells Sarah Jones
  2. 2. The Discovery of Cells In the seventeenth century, Robert Hooke looked at thin slices of cork under a microscope that he had made from lenses. He observed small box-like shapes inside the cork. He called the little boxes that he saw cells. en.wikipedia.org

  7. 7. Prokaryotic cells - simple cells without distinct membrane bound organelles or nucleus.
  8. 8. Eukaryotic cells - more complex with membrane bound organelles and nucleus.
  9. 9. Animal Cell
  10. 10. • Exist as part of a multicellular organism. • Specialisation of cells into many types (cell differentiation). • Possess nucleus and membrane bound organelles.

  12. 12. • Exist as part of a multicellular organism. • Specialisation of cells into many types (cell differentiation). • Possess nucleus and membrane bound organelles.
  13. 13. Plant vs Animal Plant and animal cells have many similarities because they are both eukaryotic. They also have some differences:
  14. 14. Parts of a Generalised Animal Cell https://en.wikipedia.org/wiki/Cell_nucleus
  15. 15. • Contains the chromosomes (genetic information) for the cell. • Controls the activities of the cell. Nucleus
  16. 16. • Double membrane - outer membrane and inner membrane. • Inner membrane is folded forming cristae. • The interior contains an organic matrix containing chemical compounds. • Site of aerobic respiration. Mitochondria
  17. 17. Rough Endoplasmic Reticulum • A membrane system of flattened parallel cavities which are interconnected and covered with ribosomes. • An intracellular transport system.
  18. 18. Golgi Apparatus • Consists of a stack of flattened cavities which package substances produced by the cell into vesicles. • These vesicles can fuse with the cell membrane (exocytosis) or become lysosomes (digestive vesicles).
  19. 19. Plant Cell Walls • The main component of plant cell walls is cellulose. • Cellulose molecules are arranged in bundles called microfibrils. • The function of the plant cell wall is to provide strength and support the plant.
  20. 20. Prokaryotic organisms are commonly called bacteria. They are cells with a simple structure. They have no membrane around the nucleus and lack any membrane bound organelles.
  21. 21. Blue-green bacteria make their own food by photosynthesis.
  22. 22. Cell Division
