1. Cell Structure & Function http://koning.ecsu.ctstateu.edu/cell/cell.html

2. Cell Theory All living things are made up of cells. Cells are the smallest parts of all living things. All cells come from other cells that divide to make new ones.

3. Definition of Cell A cell is the smallest unit that is able to do life tasks.

4. Examples of Cells One celled organism Plant Stem Red Blood Cell Nerve Cell Bacteria

5. Types of Cells We Will Study PlantAnimal

6. Parts of Cells Both cells have organelles in them. Each organelle has a special job to do to help the cell function. We will only be learning about some of the organelles. http://library.thinkquest.org/C004535/eukaryotic_cells.html

9. Cell Parts (You saw lots of cell parts, called organelles, in the preceding slides. Don’t worry we will only study the organelles on the following slides.) Are you ready? Introducing the Organelles!

10. Surrounding the Cell

11. Cell Membrane Outer membrane of cell that controls movement of nutrients, water and gases in and out of the cell http://library.thinkquest.org/12413/structures.html

12. Cell Wall In plant cells Supports & protects the cell http://library.thinkquest.org/12413/structures.html

13. Inside the Cell

14. Nucleus Directs cell activities Contains genetic material - DNA

15. Chromosomes In nucleus Made of DNA Contain instructions for traits & characteristics http://library.thinkquest.org/12413/structures.html

16. Cytoplasm Gel-like mixture All organelles are in the cytoplasm

17. Mitochondria Produces energy – by chemical reactions that break down fats & carbohydrates http://library.thinkquest.org/12413/structures.html

18. Vacuoles Sacs for storage Contains water Help plants keep shape http://library.thinkquest.org/12413/structures.html

19. Chloroplast In plant cells Contains green chlorophyll It is where photosynthesis takes place http://library.thinkquest.org/12413/structures.html
