1. Eukaryotic Cells: The Inside Story Chapter 3-3

2. Cell Membrane- surrounds all cells Keeps the cytoplasm inside Allows nutrients in and wastes products out Interacts with things outside the cell

3. Cell Wall Provides strength and support Made of cellulose in plants and algae Made of chitin in fungi Bacteria also have cell walls

4. Fungi cells have a cell wall made of a chemical similar to that found in the hard covering of insects called chitin

5. Nucleus Control center Stores DNA which has information on how to make proteins Contains the nucleolus which stores the materials that will be used to make ribosomes Largest and most visible organelle

6. Nucleus Nuclear membrane NucleolusDNA

8. F. The nucleus

9. Nucleolus stores the materials that will be used later to make ribosomes in the cytoplasm nucleolus

10. DNA is the heredity material in the cell

12. F.DNA

13. Ribosomes are protein-making sites Smallest but most abundant organelles Not covered by a membrane Uses amino acids to make proteins

15. B. Ribosomes

16. Endoplasmic Reticulum (ER) Makes lipids internal delivery system May be covered by ribosomes Looks like flattened sacks stacked side by side or a cloth folded back and forth

18. D. Endoplasmic reticulum

19. Mitochondria-cell’s powerhouse Makes ATP Surrounded by two membranes Needs oxygen Liver and muscle cells have the most mitochondria Bean-shaped Breaks down food molecules to release energy

21. G. Mitochondria

22. Chloroplast is an energy-converting organelle Found in plants and algae Chlorophyll makes them green Photosynthesis takes place in chloroplast

24. B. Enable plants to produce their own food

26. D. Chloroplasts

27. Golgi complex-organelle where proteins and other materials are processed and transported out of the cell

28. The Golgi complex processes, packages, and transports material out of eukaryotic cells

29. Vesicles Membrane covered compartments Some pinch off from the ER or Golgi bodies Others form when part of the cell membrane surrounds an object outside a cell White blood cell engulfing bacteria

30. When a smaller yeast cell is engulfed by a white blood cell, a vesicle is formed by the white blood cell

31. Vacuole Stores water and other materials Plants have large vacuoles

32. A contractile vacuole squeezes excess water out of a cell

34. G. Vacuole

35. Lysosomes Digest food particles, wastes, cell parts, and foreign invaders Contains enzymes that break down particles in vesicles Causes the tail of a tadpole to shrink and disappear

36. Organelles found in plant and animal cells Nucleus Golgi complex MitochondriaLysosome Endoplasmic reticulum Cell membrane Ribosomes

37. Organelles found only in plant cells and not in animal cells Chloroplast Large vacuole Cell wall

39. D.plant

41. A. Chloroplasts
