6. What is the function of the phloem?

  • Carries products of photosynthesis through the leaf
  • Carries water through the leaf
  • Carries CO2 through the leaf
  • Carries colorants through the leaf

7. What do nitrate ions do?

  • Growth and repair of plant
  • Part of chlorophyll molecule
  • Make amino acids, proteins, chlorophyll, and DNA
  • Used for enzymes of respiration and photosynthesis

8. Which of these is an example of a virus?

  • Pheumococcus
  • Influenza
  • Chlorella
  • Lactobactillius bulgarius

9. What 7 things do bacterium particles contain?

  • Cell wall, flagella, plasmids, cytoplasm, chromosome, cell membrane, slime layer
  • Cell wall, plasmids, cytoplasm, chloroplasts, nucleus, vacuole, slime layer
  • Cell wall, flagella, chromatids, cytoplasm, chromosome, cell membrane, slime layer
  • Cell wall, plasmids, flagella, cytoplasm, nucleus, cell membrane, vacuole

10. What is the function of the upper epidermis?

  • Contains stomata, allowing O2 to diffuse into leaf and CO2 to diffuse out
  • Contains a few chloroplasts- relatively transparent
  • Main sight of photosynthesis
  • Protective layer of leaf and barrier to harmful micro-organisms

11. What is the equation for the anaerobic respiration of yeast?

  • glucose+oxygen->carbon monoxide+water
  • glucose->ethanol+carbon dioxide
  • glucose+oxygen->carbon dioxide+water
  • glucose->lactic acid+water

12. What is the function of the palisade cells?

  • Protective layer of leaf
  • Main sight of photosynthesis
  • Main sight of respiration
  • Contains stomata

13. What is the role of the stomata in gas exchange?

  • Allow CO2 to diffuse in, and O2 to diffuse out
  • Allow O2 to diffuse in, and CO2 to diffuse out
  • No function
  • Allow spongy cells to expand and contract

14. What do magnesium ions do?

  • Make oxygen and water
  • Part of chlorophyll molecule
  • Growth and repair of plant
  • Make DNA

15. Which of these is an example of a protoctist?

  • Chlorella
  • Influenza
  • Algae
  • Lactobactillius bulgarius

16. What is the purpose of photosynthesis?

  • To release more energy by making carbon dioxide and water
  • To produce more energy by making carbon dioxide and water
  • To produce more energy by making glucose and oxygen
  • To release more energy by making glucose and oxygen

17. What enzyme is released in the stomach and what does it do?

  • Pepsin- breaks down protein into peptides
  • Protease- breaks down protein into amino acids
  • Lipase- breaks down lipids into fatty acids
  • Peptidase- breaks down peptides into amino acids

18. What is the function of the xylem?

  • Carries oxygen through the leaf
  • Carries colorants through the leaf
  • Carries water and mineral ions through the leaf
  • Carries products of photosynthesis through the leaf

19. What is the multicellular form of fungi?

  • Rod structure
  • Hyphae structure
  • Spiral structure
  • Filament structure

20. What do proteins do?

  • Brain function
  • Heart function
  • Growth and repair
  • Energy through respiration
