1. Cells Test Review Practice with these slides until you know them all!

2. What are some functions cells carry out?

3. Cells can: Get rid of body wastes Release energy from food Make new cells for growth and food Carry on photosynthesis (plant cells) Divide to make more cells

4. What is the gel-like substance inside a cell called?

5. Answer: Cytoplasm This is the thick jelly inside a cell that keeps organelles in place.

6. What is a chloroplast?

7. A chloroplast: Is oval shaped Releases oxygen Is found in the highest concentration in the cells of plant leaves Uses energy from the sun to make food Contains chlorophyll

8. What is a cell wall?

9. A cell wall: Is usually rectangular Protects a plant cell Helps the cell maintain its shape Is a strong and rigid layer

10. Both plant and animal cells:

11. Contain cytoplasm, a cell membrane, mitochondria, and a nucleus

12. What does a cell membrane do?

13. A cell membrane: Encloses the contents of the cell Is selectively permeable or absorbent Controls what enters and exits the cell

14. What is the function of the mitochondria?

15. The mitochondria: Break down food to release energy for the cell and the organism

16. What instrument contributed to the development of cell theory?

17. The instrument scientists needed was: A microscope

18. What is the function of the nucleus?

19. The nucleus: Is the brain of the cell Carries genetic material Carries DNA instructions for the cell

20. What is the function of the lysosome?

21. The lysosome: Gets rid of wastes

22. Where is the dependent variable graphed?

23. The dependent variable is graphed on the Y axis

24. What organelle does a plant cell need in order to be a producer?

25. A plant cell produces glucose: In its chloroplasts

26. How do you calculate the mean?

27. Add all the data points together, divide by the number of data points

28. What do bacteria, fish, plants and clams all have in common?

29. They are all made up of cells

30. Autotrophic means:

31. Autotrophic means Makes its own food

32. Eukaryotic means:

33. Eukaryotic means Has membrane bound structures (nucleus)

34. The simplest organisms are:

35. The simplest organisms are Unicellular prokaryotic

36. What is the purpose of cilia and flagellum?

37. Cilia and flagellum help unicellular pond organisms to move

38. Do the cells of all living things all have the same structures?

39. No, cell structures relate to the cell functions. Animal cells don’t have cell walls or chloroplasts Multicellular eukaryotic organisms (like us) cells don’t have cilia

40. What organelle helps plants maintain homeostasis in a dry climate?

41. All living things:

42. All living things are Made up of cells

43. All cells come from:

44. All cells come from pre-existing cells
