3. Who invented the compound microscope in the 1500s? Remember: He put two magnifying glasses together in a tube. Hint: His initials are Z.J.

4. Zacharias Janssen

5. Who invented a more advanced microscope than the compound microscope? This scientist’s microscope magnified objects up to 270 times their actual size.

6. Anton van Leeuwenhoek

7. Who observed slices of cork under a microscope and called the empty spaces he observed “cells”? Hint: His initials are R.H.

8. Robert Hooke

9. In the mid 1800s what scientist concluded that all animals are made up of cells? Hint: His initials are T.S.

10. Theodore Schwann

11. In the mid 1800s what German Scientist observed that plants are made of cells? Hint: His initials are M.S.

12. Matthias Schleiden

13. What are three differences between animal cells and plant cells?

14. 1. Plant cells have cell walls; Animal cell don’t. 2. Plant cells are always geometric in shape; animal cells look like blobs with no definite shape. 3. Some plant cells have chloroplasts; animal cells never have chloroplasts.

15. What is the function of the chloroplasts in a plant cell?

16. They make photosynthesis happen! Through photosynthesis, plants make their own food. DAILY DOUBLE!!

17. What are two organelles only found in plant cells?

18. Chloroplasts & Cell Walls!

19. What two plant cells did we observe under a microscope in class?

20. The onion cell & the elodea cell

21. What liquid did we need to use to see the onion cell under the microscope?

22. Iodine!

23. What do animal cells look like? What is their shape?

24. They look like blobs. They have no definite shape. DAILY DOUBLE!!

25. Why is the cell theory important?

26. The cell theory is important because it suggests that all living organisms are related.

27. Name the three parts of the cell theory.

28. 1. All living things are made of cells. 2. Cells are the basic unit of structure and function in ALL living things. 3. ALL living cells are made from other living cells.

29. Does an animal cell have a cell wall?

30. No, they don’t have cell walls, but they do have cell membranes! DAILY DOUBLE!!

31. Which organelle is called “the power house” of the cell? Hint: It releases energy needed for the cell to function properly.

32. The mighty mitochondria!

33. What organelle is the control center of the cell?

34. The nucleus!

35. What organelle contains DNA and the genetic code of heredity for the cell?

36. the chromosome!

37. What organelle is a sac that stores water, food, or waste? Hint: Plants have a large one of these that stores water.

38. Vacuole! DAILY DOUBLE!!

39. What organelle makes proteins from raw materials in the cytoplasm?

40. Ribosome!
