Test 3
1. The covering that forms the outer boundary of a cell is called the cell membrane.
Quiz 3A
2. The cell membrane protects the cell from harmful substances but allows the needed materials into the cell.
Quiz 3A
3. cytology—the study of cells
Quiz 3A
4. In the fluid mosaic model, the cell membrane is made of the molecules protein and lipids.
Quiz 3A
5. Hydrophilic—something that likes to be in water.
Quiz 3A
6. Hydrophobic—avoids contact with water
Quiz 3A
7. Living cells require water environments.
Quiz 3A
8. A selectively permeable membrane allows some molecules to pass through but not others.
Quiz 3A
9. Water, oxygen and carbon dioxide are small and pass through membranes.
Quiz 3A
10. Starch and protein molecules are large and only pass through certain membranes.
Quiz 3A
11. transport—movement through a cell
Quiz 3A
12. Passive transport—movement of substances through a membrane without the use of the cells own energy.
Quiz 3A
13. Diffusion is an example of passive transport (not a type of osmosis).
Quiz 3A
14. In osmosis, water moves from an area of higher concentration to an area of lower concentration.
Quiz 3A
15. Diffusion and osmosis are examples of passive transport.
Quiz 3A
16. Active transport requires the cell to use energy.
Quiz 3A
17. Anton van Leeuwenhoek was recognized as an honorary member by the Royal Society of London because of his outstanding work in making an using lenses to see tiny organisms.
Quiz 3A
Quiz 3A
covers notes:1, 3, 4, 5, 8,
12, 13, 14, 16, 17
18. All cells need energy.
Quiz 3B
19. Cells have three basic parts:a. Cell Boundariesb. Cytoplasmc. Genetic Material
Quiz 3B
20. All cells have an outermost boundary called the cell membrane.
Quiz 3B
21. The cell membrane protects the cells inside and controls what enters and exits the cell.
Quiz 3B
22. Plant cells are different from animals cells because their boundaries include a structure called a cell wall.
Quiz 3B
23. The diaphragm on a microscope is used to adjust the amount of light passing through the specimen.
Quiz 3B
24. 10 X eyepiece
x 40 X objective
400 X total magnification
Quiz 3B
25. cytoplasm—thick fluid that contains small organelles
Quiz 3B
26. organelles—parts of a cell that perform many functions needed to keep the cell alive
Quiz 3B
27. mitochondria—produces usable energy for the cell
Quiz 3B
28. Ribosomes manufacture proteins
Quiz 3B
29. Vacuoles store material.
Quiz 3B
30. Lysosomes dispose of worn-out cell parts.
Quiz 3B
31. Chloroplasts—organelles in which photosynthesis occurs
Quiz 3B
32. Turgor pressure results from the build up of water in the central vacuole.
Quiz 3B
33. The nucleus contains the cells genetic information.
Quiz 3B
Quiz 3B covers notes:22-24, 27-33
34. Algae plants and humans have eukaryotic cells—not bacteria.
Quiz 3C
35. All animals cells are eukaryotic.
Quiz 3C
36. The eukaryotics genetic material is surrounded by a membrane.
Quiz 3C
37. The genetic material of staphylococcus aureus is a prokaryotic (bacteria) because it is contained in a nuclear area that is not surrounded by a nuclear membrane.
Quiz 3C
38. Prokaryotic cells have genetic material.
Quiz 3C
39. Some organelles may be missing in some cells.
Quiz 3C
40. Prokaryotic cells do not have mitochondria.
Quiz 3C
41. Eukaryotes and prokaryotic cells have cell walls.
Quiz 3C
42. Chloroplast are found in some eukaryotic cells but not all of them.
Quiz 3C
43. An example of irreducible complexity is when a cell cannot survive without ribosomes for making proteins.
Quiz 3C
Quiz 3C
