3. A. CELL THEORY 1)All living things are made of one or more cells. 2)Cells are the basic unit of structure and function in living things. 3)Living cells come only from other living cells.

4. These cells have a nucleus. Nucleus is a membrane covered organelle that holds the DNA. Examples are plant and animal cells. B)Two Types of Cells: These cells DO NOT have a nucleus. DNA exists in loops that floats freely in the cell. An example is bacteria

5. Prokaryotic Cell Eukaryotic Cell

6. C)ANIMAL VS. PLANT CELLS: Large No Cell wall Small Vacuoles No Chloroplasts Cell wall Large Vacuoles Chloroplasts

7. Elodea leaf “Tiny Solar Panels”

8. 1) ORGANELLES: tiny organs in the cell. 2) CYTOPLASM: fluid filling inside the cell membrane. makes up the majority of cell’s mass. C)SOME CELL TERMS & STRUCTURES:

9. Organelles Cytoplasm

10. 3) CELL MEMBRANE controls movement of materials into and out of the cell holds cell together Cell membrane Animal Cell

11. Cell membrane Animal Cell

12. Phospholipids Cell membrane Animal Cell

16. Phospholipids Cell membrane Animal Cell

17. Plant Cell

18. Cell wall Cell membrane Plant Cell

19. found in plant cells not animal cells provides strength and support for plant cells. made of cellulose (long chains of sugar molecules) 4) CELL WALL

21. 1) Nucleus: the control center of the cell stores DNA (a)nucleolus - dark spot inside the nucleus, which makes ribosomes. C)ORGANELLES OF CELLS:

22. Nucleus Nuclear membrane DNA Nucleolus Animal Cell

23. (b)nuclear membrane - controls movement of materials in and out of nucleus. (c) DNA - stores information for making proteins

24. 2) RIBOSOME tiny grain like particles usually found along the E.R. proteins are made here Ribosome Proteins Amino acids

25. Endoplasmic reticulum Endoplasmic reticulum Animal Cell

26. Endoplasmic reticulum Endoplasmic reticulum Ribosome Animal Cell

27. 3) Endoplasmic Reticulum (ER): makes lipids the delivery system of the cell for compounds such as proteins through its tubular connections.

28. 4) Mitochondria: the “Power House” of the cell releases energy packets of ATP for use in the cell. Mitochondria Outer membrane Inner membrane

29. 5) Chloroplast: “Solar Panels” for capturing energy they use energy from sunlight to make food in plant cells (i.e. glucose). Outer membrane Inner membrane Chloroplast

30. Cell membrane Mitochondria Chloroplast Vacuole Plant Cell

31. Vacuole 6) Vacuole: “Storage Tanks” of the cell store water, food and waste. Animal Cell Plant Cell

32. Animal Cell

33. 7) Golgi body: packages and transports materials out of the cell. Golgi complex Animal Cell

34. 8) Lysosome: “Clean-up and Recycling Crew” digest food particles, wastes, cell parts, and foreign invaders. Lysosome Vesicle with food Animal Cell

36. 1)You will be able to do the following: List 3 parts of cell theory. List 2 cell types & one characteristic for each. List 3 differences between plant and animal cells. 2) You will practice the following language objectives: Listen and write notes about cells. Discuss with lab partner and class the key points of today’s lesson. Today’s Objectives:
