1. Cell -Structure and Function

2. Discovery of the Cell

3. Microscope

4. Basic Components of Cell
Cell Membrane
Cytoplasm
Nucleus Animal cell

5. Nucleus
Cytoplasm
Cell wall

6. Cell Membrane

7. Cytoplasm

8. Nucleus

9. Functions of Nucleus
 Controls all metabolic activities of the
cell
 It is responsible for cell division
 It is responsible for transmission of
hereditary material from one
generation to another

10. Prokaryotic Cells
 Nucleus is not well organized
 Lack nuclear membrane and
nucleolus
 Nuclear region is known as nucleoid
 e.g. Bacteria. Blue green algae

12. Eukaryotic Cell
 Have a well organized nucleus with a
nuclear membrane
 e.g. plant and animal cells

13. Cell Wall
Cell wall

14. Multicellular Organisms

15. Unicellular Organisms

16. Shape of Cells
Spindle shape
Long and Branched

17. Shape of Cells

18. Shape of Cells
Slipper shaped

19. Size of Cells
 Some cells are visible to the unaided eye
 Smaller cells are easily visible under a
light microscope
