Life Science Test 3

Quiz 3 A 1. The covering that forms the outer boundary of a cell is called the cell membrane.

Quiz 3 A 2. The cell membrane protects the cell from harmful substances but allows the needed materials into the cell.

Quiz 3 A 3. cytology—the study of cells

Quiz 3 A 4. In the fluid mosaic model, the cell membrane is made of the molecules protein and lipids.

Quiz 3 A 5. Hydrophilic— something that likes to be in water.

Quiz 3 A 6. Hydrophobic— avoids contact with water

Quiz 3 A 7. Living cells require water environments.

Quiz 3 A 8. A selectively permeable membrane allows some molecules to pass through but not others.

Quiz 3 A 9. Water, oxygen and carbon dioxide are small and pass through membranes.

Quiz 3 A 10. Starch and protein molecules are large and only pass through certain membranes.

Quiz 3 A 11. transport— movement through a cell

Quiz 3 A 12. Passive transport— movement of substances through a membrane without the use of the cells own energy.

Quiz 3 A 13. Diffusion is an example of passive transport (not a type of osmosis).

Quiz 3 A 14. In osmosis, water moves from an area of higher concentration to an area of lower concentration.

Quiz 3 A 15. Diffusion and osmosis are examples of passive transport.

Quiz 3 A 16. Active transport requires the cell to use energy.

Quiz 3 A 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 3 A covers notes: 1, 3, 4, 5, 8, 12, 13, 14, 16, 17

Quiz 3 B 18. All cells need energy.

Quiz 3 B 19. Cells have three basic parts: a. Cell Boundaries b. Cytoplasm c. Genetic Material

Quiz 3 B 20. All cells have an outermost boundary called the cell membrane.

Quiz 3 B 21. The cell membrane protects the cells inside and controls what enters and exits the cell.

Quiz 3 B 22. Plant cells are different from animals cells because their boundaries include a structure called a cell wall.

Quiz 3 B 23. The diaphragm on a microscope is used to adjust the amount of light passing through the specimen.

Quiz 3 B 24. 10 x 40 X eyepiece X objective 400 X total magnification

Quiz 3 B 25. cytoplasm—thick fluid that contains small organelles

Quiz 3 B 26. organelles—parts of a cell that perform many functions needed to keep the cell alive

Quiz 3 B 27. mitochondria— produces usable energy for the cell

Quiz 3 B 28. Ribosomes manufacture proteins

Quiz 3 B 29. Vacuoles store material.

Quiz 3 B 30. Lysosomes dispose of worn-out cell parts.

Quiz 3 B 31. Chloroplasts— organelles in which photosynthesis occurs

Quiz 3 B 32. Turgor pressure results from the build up of water in the central vacuole.

Quiz 3 B 33. The nucleus contains the cells genetic information.

Quiz 3 B covers notes: 22 -24, 27 -33

Quiz 3 C 34. Algae plants and humans have eukaryotic cells—not bacteria.

Quiz 3 C 35. All animals cells are eukaryotic.

Quiz 3 C 36. The eukaryotics genetic material is surrounded by a membrane.

Quiz 3 C 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 3 C 38. Prokaryotic cells have genetic material.

Quiz 3 C 39. Some organelles may be missing in some cells.

Quiz 3 C 40. Prokaryotic cells do not have mitochondria.

Quiz 3 C 41. Eukaryotes and prokaryotic cells have cell walls.
