1. Organisms
Are made of Organ Systems

2. Organ Systems
Are made of Organs (illustration of the organs in a fish’s vascular system)

3. Organs
Are made of Tissues (heart tissue)

4. Tissues
Are made of Eukaryote Cells

5. Eukaryote Cells
Are made of Parts

6. Each cell part has a role in
Performing the Cell’s Job, which is to
Help an organism survive!

7. Structure of a eukaryote cell
Protective layer or layers surrounding the cell’s interior (cell wall/cell membrane)
Cytoplasm
Organelles within the cytoplasm
Nucleus

8. All Cells have a Cell Membrane

9. The Cell Membrane Protects the cell
Allows only certain materials to enter and exit the cell – selectively- permeable
Made of a lipid bi-layer*.
Activity: Making a cell membrane

10. The Cell Membrane Cell membrane is embedded with proteins
Protein molecules create “tunnels” through the cell membrane that allow particles to enter and exit the cell.
Receptor protein molecules send messages around the body from cell to cell*.

11. Nucleus

12. The Nucleus
Made of
Nuclear Membrane/Envelope surrounding the nucleus (selectively permeable)
Chromosomes – composed of DNA wrapped around proteins
Nucleolus – produces ribosomes

13. The Nucleus DNA determines which proteins the cell produces
how much of each protein the cell produces

14. Cytoplasm

15. Cytoplasm Semi-fluid material enclosed by the cell membrane
Organelles float in this material

16. Organelles
A membrane-bound compartment or structure in a cell that performs special functions. A

17. Free Ribosomes

18. Rough Endoplasmic Reticulum with Ribosomes attached

19. Ribosomes and the Rough Endoplasmic Reticulum
Ribosomes: Protein synthesis occurs here
Rough ER: covered with ribosomes
Once protein molecules are made, the rough ER folds and shapes the molecules for use by the cell*

20. Mitochondrion(a)

21. Mitochondrion Cell respiration occurs here!
Cell respiration releases ENERGY from molecules of food
This energy is used for all cell functions

22. Cytoskeleton

23. Cytoskeleton
A network of fibers that provides physical support and structure to the cell
Made of microtubules and microfilaments.

24. Cytoskeleton The cytoskeleton is responsible for cell shape
movement of organelles in the cell.
movement of the cell as a whole (in one celled organisms)*

25. Certain Cell Parts are found in Plant OR Animal cells (not both)
Plant Cells
Animal Cells

26. Animal Cells have organelles called Lysosomes

27. Digest cellular waste and old/useless molecules and organelles.
Lysosomes
Digest cellular waste and old/useless molecules and organelles.

28. Animal Cells have organelles called Centrioles

29. Play a role in reproduction of animal cells
Centrioles
Play a role in reproduction of animal cells

30. Plant Cells have organelles called Chloroplasts

31. Chloroplasts Site of photosynthesis in plant cells
Photosynthesis produces carbohydrates*

32. Plant Cells have Cell Walls

33. Cell Walls Provide support and protection for cell
Provide rigidity to cell – allow plants to be tall without a skeleton
Found in plants, fungi, algae and most prokaryote cells.

34. Cell Walls Made of carbohydrates and protein.
One type of carbohydrate is cellulose = wood and paper.
The presence of cell walls allows large plants to stand tall without a skeleton.
Selectively permeable

35. Plant Cells have Large Central Vacuoles

36. Large Central Vacuoles
Provides storage for water, salts, waste in plants
Animal cells have multiple small vacuoles (not located in center of cell)

37. The Cell as a Factory

38. The Inner Life of a Cell

39. Summary – Use your notes
Make a Venn Diagram showing which cell parts are found only in Animal Cells, only in Plant Cells and in both types of cells.
Which cell parts are necessary for the physical structure of the cell?
Beginning with the nucleus and ending with the Golgi Apparatus  Make a table: Name and describe the job of cell parts related to making proteins.
Name and describe the job of cell parts related to food and energy.
