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

3. Cell Theory All living things are made up of cells. Cells are the smallest working units of all living things. All cells come from preexisting cells through cell division.

4. “TYPICAL” ANIMAL CELL

5. “TYPICAL” PLANT CELL

6. Organelles

8. CELL MEMBRANE Outer layer that controls movement of materials into and out of cell

9. CELL WALL Most commonly found in plant cells and bacteria PLANT CELL Provide Protection and Support BACTERIA CELL

11. Nucleus Directs cell activities Contains genetic material – chromosomes, DNA

12. Cytoplasm Gel-like mixture makes up inside of cell Holds other organelles in cell Surrounded by cell membrane

13. Mitochondria Functions in energy production through chemical reactions

14. VACUOLES Membrane-bound sacs for storage, digestion, and waste removal Contains water solution Help plants maintain shape

15. CHLOROPLAST Usually found in plant cells Contains green chlorophyll Where photosynthesis takes place

16. Chloroplast Found in Autotrophs Autotrophic organisms make their own food

17. He’s Green. Is he an Autotroph?

18. HETEROTROPHS Organisms that do not make their own food Rely on other organisms

19. Examples of Cells Amoeba Proteus Plant Stem Red Blood Cell Nerve Cell Bacteria

20. Prokaryotic Eukaryotic

21. Prokaryotic Do not have structures surrounded by membranes Few internal structures One-celled, simple organisms, Bacteria http://library.thinkquest.org/C004535/prokaryotic_cells.html

22. Eukaryotic Contain organelles surrounded by membranes Most living organisms (you!) PlantAnimal http://library.thinkquest.org/C004535/eukaryotic_cells.html
