naked eye.

life sciences topic two(cells)

  1. 1. KLAAS Y
  2. 2. TABLE OF CONTENT • THE MICROSCOPE • CELL THEORY • DIFFERENT TYPES OF CELLS • ANIMAL AND PLANT CELL IN DETAIL • ORGANELLES
  3. 3. THE STUDY OF CELLS
  4. 4. A Microscope is an instrument used to view objects that are too small to be seen by the naked eye.
  5. 5. TYPES OF MICROSCOPES • HAND LENSES • SINGLE LENS MICROSCOPE • LIGHT MICROSCOPE • ELECTRON MICROSCOPES  SEM – Scanning electron microscope  TEM – Transmission electron microscope.
  6. 6. Robert Hook used the concept cell for the first time Robert Brown was the first to describe the nucleus in the cell Matthias Schleiden Theodor Schwann developed the cell theory Rudolph Virchow and August Weismann expanded the cell theory Schleiden, Schwann and Virchow compiled the cell theory
  7. 7. The cell theory states that:  All living organisms are made out of cells  New cells are formed by the division of existing cells  The cell houses genes, which are the blueprint for growth, functioning and development of cells  The cell is the functional unit of life because all chemical reactions of life take place inside the cell
  8. 8. A cell is the basic unit of structure and function in organisms.
  9. 9. THERE ARE TWO TYPES OF CELLS DISCOVERED TODAY. Prokaryotic AND Eukaryotic CELLS Prokaryotic CELL Eukaryotic CELL
  10. 10. Prokaryotic CELLS these are cells that do not have a true nucleus, cells without a membrane bound nucleus. Only organisms of the domains Bacteria and Archaea consist of prokaryotic cells (KINGDOM MONERA)
  11. 11. Eukaryotic CELLS • Eukaryotic cells are cells that have a true nucleus, these cells have a membrane bound nucleus. • Protists, fungi, animals and plants all consist of eukaryotic cells
  12. 12. PLANT CELL IN DETAIL
  13. 13. ANIMAL CELL IN DETAIL
  14. 14. ORGANELLES Organelles (are very small) microscopic structures found within a cell These perform various functions for the cell They are flouting in the cytoplasm They may or not be membrane bound
  15. 15. What do organelles do? ★process energy ★manufacture substances needed by the cell ★move materials ★act as storage site
  16. 16. The nucleus Enclosed by a nucleomembrane with nuclear pores for Protection of nucleoplasm, nucleolus and chromatin
  17. 17. Chloroplasts contain green pigment chlorophyll chlorophyll captures light energy that is used to make glucose, chloroplast contain the following: Ribosomes, starch grains, grana, Stroma, thylakoids double membrane.
  18. 18. MITOCHONDRION Consist of 2 membranes: Outer – and a highly convoluted inner membrane- These folds are called cristae – they increase the surface area. Filled with matrix called stroma that contains DNA and ribosomes. Function: Produce energy in the form of ATP by means of cellular respiration
  19. 19. Cell wall
  20. 20. CELL MEMBRANE Consist of 2 phospholipid layers and proteins in between. The phospholipid layers are part hydrophilic and part hydrophobic
