4. Column 1, #1 Who was one of the first people to identify and see cork cells? Robert Hooke.

5. Column 1, #2 Prokaryotes (i.e. bacteria) are cells that do not contain nuclei and are generally smaller and simpler than eukaryotes. Eukaryotes (i.e. plants, animals) are cells that contain nuclei and organelles. What are the characteristics of prokaryotes and eukaryotes? Give an example of a prokaryote and eukaryote.

6. Column 1, #3 Describe Theodor Schwann’s contribution to the cell theory. In 1839, Theodor Schwann stated that all animals are made up of cells.

7. Column 1, #4 Describe Matthias Schledien’s contribution to the cell theory. In 1838, German botanist Matthias Schleiden concluded that all plants were made of cells.

8. Column 1, #5 1.All living things are composed of cells. 2.Cells are the basic units of structure and function in living things. 3.New cells are produced from existing cells. Describe the three parts of the cell theory.

9. Column 2, #1 1000 x Electron microscopes are capable of revealing details as much as _________ times smaller than those visible in light microscopes.

10. Column 2, #2 Total magnification = eyepiece x objective What is the equation for determining total magnification?

11. Column 2, #3 The microscope slide is held in place using the stage clips. Which microscope structure is a rectangular piece of glass on which the specimen is placed? How is it held in place?

12. Column 2, #4 diaphragm Which microscope structure allows you to adjust the intensity of the light?

13. Column 2, #5 Why are electron microscopes capable of revealing details much smaller than those seen through a light microscope? The wavelengths of are much shorter than those of light.

14. Column 3, #1 Describe the function of the nucleus. What is chromatin? The nucleus contains nearly all the cell’s DNA and with it the coded instructions for making proteins and other important molecules. Chromatin is the granular material you can see in the nucleus. Chromatin consists of DNA bound to protein.

15. Column 3, #2 Which organelle converts the chemical energy stored in food into compounds that are more convenient for the cell to use? Mitochondrion.

16. Column 3, #3 What is the function of the lysosome? Lysosomes are small organelles filled with enzymes that serve to digest, or breakdown, lipids, carbohydrates, and proteins into small molecules that can be used by the cell. They are also involved in breaking down organelles that have outlived their usefulness.

17. Column 3, #4 The cytoskeleton helps a cell keep its shape, is involved in movement of the cell, and is important in cell division. Describe the functions of the cytoskeleton.

18. Column 3, #5 Proteins are produced in the rough endoplasmic reticulum and next move to the Golgi apparatus, which modifies sorts, and packages proteins for storage or secretion. Describe the path of a protein in the cell.

19. Column 4, #1 Which organelle serves as the cell’s boundary from the environment? Cell Membrane

20. Column 4, #2 The movement of molecules from an area of high concentration to an area of low concentration. Define diffusion.

21. Column 4, #3 The concentration of molecules on both sides of the membrane is the same. Molecules move across the membrane in both directions. At equilibrium, which direction do molecules move?

22. Column 4, #4 The freshwater is hypotonic to the cell. Water will rush into the cell, causing it to burst. What will happen to an animal cell surrounded by fresh water?

23. Column 4, #5 Which means of particle transport requires input of energy from the cell? Active Transport

24. Column 5, #1 Define cell specialization. What kind of organisms is this characteristic of? Cells throughout a multicellular organism can develop in different ways to perform different tasks.

25. Column 5, #2 Which term describes a group of similar cells that perform a particular function? Tissue.

26. Column 5, #3 A group of organs that work together to perform a specific function. What is an organ system?

27. Column 5, #4 Cell, Tissue, Organ, Organ System Name the levels of organization in a multicellular organism from the simplest level to the most complex level.

28. Column 5, #5 Name the four main types of tissue? 1.Muscle 2.Epithelial 3.Nervous 4.Connective
