  2. 1. What does a group of cells working together create? • Tissues

  3. 2. Sequence these words from most complex to most simple: cell, organism, organ, organ system, tissue, • Organism > organ system > organ > tissue > cell

  4. 3. What do plants, animals, and protist all have in common? • All are made up of cells

  5. 4. What are some similar functions that all cells carry on? • Reproduce • Have a nucleus • Can move

  6. 5. Illustrate the cell theory using pictures of the levels of organism for plants, animals, and protist.

  7. 6. What are the major differences between organelles found within plant and animal cells? • Plant Cells: • Cell wall • Chloroplasts • Large vacuole Animal Cells: - no cell wall - small vacuoles - have

  8. 7. Compare and contrast the structure or organelles found in plant cells to those found in animal cells.

  9. 8. Compare and contrast the function of organelles found in plant cells to those found in animal cells. http://www.biologyjunction.com/cell_functions.htm

  10. 9. Which organelles in plants are involved in the process of photosynthesis? • Chloroplasts

  11. 10. What part of a plant does water travel through to reach the leaves? • xylem

  12. 11. How would photosynthesis be affected if xylem was not present in vascular plants? • Would not be able to transfer water • -no turger pressure

  13. 12. What is the function of the bulb in a plant? • food reserves that enable a plant to lie dormant when water is unavailable (during winter or drought) and resume its active growth when favorable conditions again prevail
