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

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

3. Examples of Cells Amoeba Plant Cell Red Blood Cell Nerve Cell

4. Organelles Organelles are the parts of the cell that perform different functions. There are 11 main organelles (9 for animal cells)

5. “Typical” Animal Cell http://web.jjay.cuny.edu /~ acarpi/NSC/images/cell.gif

6. http://waynesword.palomar.edu/images/plant3.gif “Typical” Plant Cell

7. Cell Parts Organelles

8. Surrounding the Cell

9. Cell Wall Gives shape and support to cell Plants and protists, like algae, have cell walls Fungi, like yeasts and mushrooms, also have cell walls Bacteria and Archae also have cell walls, but they are different from plant and fungi Animal cells DO NOT have cell walls

10. Cell Membrane “Gatekeeper” of the cell that controls what can come in or out of the cell Semi-permeable

11. Inside the Cell

12. Nucleus Controls the cell’s activities It’s like the “boss” or the “brains” of the cell DNA is found inside the nucleus

13. Nuclear Membrane The “gatekeeper” of the nucleus Protects the outside of the nucleus Controls what can go in or out of the nucleus

14. Chromosomes Long pieces of DNA inside the nucleus Come in pairs-one from your mom and one from your dad Humans have 23 pairs of chromosomes, 46 total chromosomes

15. Cytoplasm Soupy, Jell-O like substance that holds all organelles inside the cell in place

16. Ribosomes Each cell contains thousands Make proteins for the cell

17. Mitochondria Makes energy (ATP) by breaking down fats and carbohydrates Controls level of water and other materials in cell If your mitochondria wasn’t working properly, you wouldn’t be making enough energy and may feel very tired!!

18. Lysosomes Digest proteins, fats, and carbohydrates Clean up cell’s waste by sending them to the cell membrane for disposal

19. Vacuoles Storage centers for both plant and animal cells Much larger in plant cells because of the storage of water Gives plant cells shape (along with cell wall)

20. Chloroplast ONLY found in plant cells Contains chlorophyll, which is where plants get their green pigment Where photosynthesis takes place

21. Match That Part! Cell Membrane Cell Wall Chloroplasts Mitochondria Ribosomes Lysosomes Vacuole Chromosomes Nucleus Nuclear Membrane Cytoplasm Controls what goes in/out of nucleus Controls cell activities Creates proteins for cell Contains/long pieces of DNA Gives the cell shape and support Controls what goes in/out of cell Contains chlorophyll for photosynthesis Storage of food and water Gobbles up the waste Jell-O like substance that holds parts in place Produces energy for the cell

22. How to Write an Analogy An analogy is a comparison between two seemingly unlike things, using the words like or as and giving an explanation. For example: -The nucleus is to a cell as Mrs. Opferman is to Webb Bridge Middle School Now you practice will cell parts! –The nucleus is to a cell as _______is to a ________________.

23. Animal Both Plant
