1. What are Cells Made up of? Cells are made of cell organelles

3. How are they different? Plant cells are green and box-like Animal cells are not green and are round

4. How are they alike? Both contain cell organelles (nucleus) Each cell organelle has its own function!

9. Cell (plasma) Membrane (A & P) Surrounds the cell Regulates what is allowed in and out of the cell (club bouncer!) This is called selectively permeable or semipermeable It is sometimes referred to as the phospholipid bilayer

10. The Cell Membrane The outer surface contains receptor molecules Allows cells to communicate with each other. Communication allows cells to maintain homeostasis.

11. Can I come in? The cell membrane controls what goes in and out. There is one main factor that determine whether or not a substance can pass through a cell membrane –SIZE- Smaller molecules pass through much easier than larger molecules

12. Cytoplasm (A & P) Jelly-like fluid inside the cell

13. Nucleus (A & P) The control center “brain” for cell functions Contains DNA (genetic material) Contains nucleolus which is involved in the production of ribosomes

14. Nucleus Nuclear Membrane

15. Ribosomes (A & P) Involved in the synthesis (making) of proteins They are either free-floating or Attached to the Endoplasmic Reticulum (ER)

16. ribosomes help create proteins! Popeye is active because he eats spinach. However, for Popeye’s cells to be active, his ribosomes help create proteins!

17. Endoplasmic Reticulum (ER) (A & P) Helps in the life process of transport Rough ER has ribosomes and aids in the production of proteins Smooth ER has no ribosomes and aids in the production of fats

20. Mitochondria (A & P) Power House of the cell Process of Cellular Respiration takes place here. This converts Oxygen and nutrients into ENERGY known as ATP

21. The Powerhouse of the Cell!

22. Vacuole (A & P) Very small in animal cells and VERY large in plant cells They are storage sacs that hold water and food.

24. Lysosomes Found ONLY in animal cells Produced by the Golgi Bodies Break down old cell organelles Helps fight infection or disease

25. Lysosome Animation

26. Centrioles Found only in animal cells Located near the nucleus Involved in cell division (reproduction )

29. Remember: Plants cells contain the same organelles as animal cells do:  Cell Membrane  Cytoplasm  Nucleus/Nucleolus  Ribosomes  Rough and Smooth ER  Mitochondria  And Vacuoles

30. NOT But they also contain the following organelles NOT found in animal cells : Cell Wall (different from cell membrane) Chloroplasts (green color) Larger Vacuole

32. Cell Wall Found only in plant cells The cell wall is relatively rigid. Provides support and shape for the cell

33. Cell Wall

34. Chloroplast Found only in plant cells Contains chlorophyll Is necessary to carry out photosynthesis

35. Chloroplasts

36. Plant Vacuole Plant Vacuole Very large in plant cells Holds excess water in the cells

38. Name 3 structural differences between a plant & animal cell. Animal cells are round, plant cells box-like Plant cells contain a cell wall, chloroplasts, and a larger vacuole Animal cells contain lysosomes and centrioles

39. In Multicellular Organisms… Organelles work together to make up CELLS Cells are grouped together to form TISSUES Tissues can be combined to make ORGANS And different organs can work together as an ORGAN SYSTEMS

42. 2. Golgi Bodies 3. Nucleolus 4. Nucleus 5. Centrioles 6.Cytoplasm 7. Ribosome 8. Lysosome 9. Rough ER 10. Smooth ER 11. Cell Membrane 1. Mitochondria

43. In Conclusion… Cells may have different structures (shapes) and different functions (jobs), but ALL cells must work together in a coordinated manner to carry out the processes of life.
