1. Cell Structure and Function

2. All Living things are made up of cells
Cell Theory
All Living things are made up of cells
Cells are the smallest working units of all living things
All cells come from pre- existing cells through cell division

3. Cell
A cell is the smallest unit that is capable of performing life functions

4. Examples of Cells
Nerve Cell
Red Blood Cell Bacteria

5. “Typical” Animal Cell

6. “Typical” Plant Cell

7. Cell Parts

8. Cell Membrane
Outer membrane of cell that controls movement in and out of the cell
Double layer

9. Cell Wall Most commonly found in plant cells & bacteria
Supports & protects cells

10. Inside the Cell

11. Nucleus
Controls center of the cell
Contains genetic material - DNA

12. Nuclear Membrane Surrounds nucleus Made of two layers
Openings allow material to enter and leave nucleus

13. Nucleolus
Inside nucleus
Contains RNA to build proteins

14. Cytoplasm
Gel-like material between the nucleus and cell membrane

15. Endoplasmic Reticulum
Moves materials around in cell
Smooth type: lacks ribosomes
Rough type ribosomes embedded in surface

16. Ribosomes Each cell contains thousands Make proteins
Found on ribosomes & floating throughout the cell

17. Mitochondria
Releases energy from nutrients

18. Golgi Bodies
Area that stores and packages chemicals

19. Lysosome
Transports undigested material to cell membrane for removal

20. Vacuoles
Membrane- bound sacs for storage, digestion, and waste removal

21. Chloroplast Usually found in plant cells Contains green chlorophyll
Where photosynthesis takes place

22. Centriole
Found in most animal cells
