  1. International School Manila SL Biology: Cells

  2. #1 The cell theory states that all cells are the smallest Unit of life, all organisms are made up of cells, and… All cells contain a nucleus All cells come from Pre-existing cells A: B: Cells need a membrane to protect it from its environment Cells are gnarly! C: D:

  3. B

  4. #2 Cells show emergent properties meaning….. They are the basic building blocks or all living things. They stick together to form multi cellular organisms A: B: The whole is greater than the sum of the parts. They have evolved to perform similar functions C: D:

  5. C

  6. #3 The size of a molecule is 1nm, and the size of a Virus is 10nm, what are the sizes of prokaryotic and a eukaryotic cell? 1µm, and 100µm 100nm, and 1000µm A: B: 10µm, and 1000µm 1nm, and 100µm C: D:

  7. A

  8. #4 Why is surface area to volume ratio important to Limiting a cell’s size? When the cell grows the surface area increases more rapidly than the volume Metabolism depends on the volume of the cell A: B: As it grows the ratio decreases not allowing the cell to receive enough nutrients or expel enough waste As it grows the ratio increases not allowing the cell to receive enough nutrients or expel enough waste C: D:

  9. C

  10. #5 Cellular differentiation is important to multi-cellular Organisms because…. Cells performing different functions and cooperate to allow an organism to perform functions beyond one cell type. They perform different functions based on chemical responses A: B: Many functions allow a cell to divide at faster rates Cells are not differentiated C: D:

  11. A

  12. #6 Stem cells are used for therapeutic purposes because They can grow very fast They are easy to obtain A: B: They contain all the necessary genetic information Have the ability to differentiate C: D:

  13. C

  14. #7 Prokaryotic cells contain….. Cell wall, cytoplasm, plasma membrane, nucleoid, pili, and 80S ribosomes Cell wall, cytoplasm, plasma membrane, nucleus, pili, and 70S ribosomes A: B: Cell wall, cytoplasm, plasma membrane, nucleoid, pili, and 70S ribosomes Cell wall, cytoplasm, plasma membrane, complex DNA, pili, and 80S ribosomes C: D:

  15. D

  16. #8 The Golgi apparatus Processes proteins and ships them out of the cell Synthesizes proteins A: B: Receives ATP from the mitochondria Receives complete proteins from the ER C: D:

  17. A

  18. #9 The cell’s membrane is composed of… A hydrophobic outer layer, a hydrophilic inner layer with integral proteins, peripheral proteins, and cholesterol A hydrophobic inner layer, a hydrophilic outer layer with integral proteins, peripheral proteins, and cholesterol A: B: A hydrophobic inner layer, a hydrophilic outer layer with integral proteins, peripheral proteins A hydrophobic outer layer, a hydrophilic inner layer with integral proteins, peripheral proteins C: D:

  19. B

  20. #10 Functions of membrane proteins are…. Channels for passive transport Hormone binding sites A: B: Pumps for active transport All of the above C: D:

  21. D

  22. #11 Osmosis is… Diffusion of substances from high concentrations to low Diffusion of water molecules from higher solute concentrations to a region of lower solute concentrations A: B: Diffusion of water molecules from lower solute concentrations to a region of higher solute concentrations Water diffusing from high concentrations to low areas of lower concentrations C: D:

  23. C

  24. #12 Active transport allows cells to move particles against the concentration gradient. The Na+ and K+ Allows the cell to Maintain cell volume, maintain osmotic balance, and use K+ for energy Maintain cell volume, maintain osmotic balance, and use change ATP to ADP A: B: Maintain cell volume, maintain osmotic balance, and maintain a steep concentration gradient of Na+ and K+ Maintain a small concentration gradient of Na+ and K+ C: D:

  25. D

  26. #13 Pinocytosis is Large solid particles entering the cell through vesicles Fluids entering the cell through vesicles A: B: The breakdown of bacteria cells in the cell by the lysosomes Liquids exiting the cell through vesicles C: D:

  27. A

  28. #14 What is the process that breaks down ATP? Hepalysis Hydroxolysis A: B: Hydrolysis Hydralysis C: D:

  29. C

  30. #15 What object is present in plant cell cytokinesis But absent in animal cell cytokinesis? Metaphase plate Glycoproteins A: B: Mitochondria Cell Plate C: D:

  31. D
