  3. What molecules are transported by Exocytosis • Wastes and proteins for export

  4. What molecules are transported by phagocytosis? • Large particles of food and bacteria

  5. What molecules are transported by pinocytosis? • Large quantities of liquids with ions and small particles

  6. What are the 3 parts of a cell life cycle? • Interphase • Mitosis • Cytokinesis

  7. What is the purpose of mitosis? • Growth • Create 2 identical daughter cells

  8. What is the 1st phase of mitosis? • Prophase

  9. What is the longest phase of mitosis? • Anaphase

  10. What phase of mitosis do chromatids line up along the equator? • metaphase

  11. When does the nuclear envelope disappear and the chromatin coil up to form chromosomes? • prophase

  12. When does the DNA replicate, or make a copy of itself? • interphase

  13. What is the longest part of the cell cycle? • interphase

  14. How many daughter cells are generated by each cell in mitosis? • 2

  15. What would happen if the centrioles did not form spindle fibers? • The chromatids would not align and separate into the 2 daughter cells

  16. What would happen if cytokinesis did not take place? • The 2 daughter cells would stay together.

  17. What are the 4 types of passive transport you looked at today? • Simple diffusion • Carrier mediated fac. Diff. • Channel mediated Fac. Diff. • Osmosis

  18. What molecules are transported by simple diffusion? • Small lipid soluble molecules; CO2; O2; chloride ions; vitamins

  19. What molecules are transported by carrier-mediated facilitated diffusion? • Lipid insoluble solutes; • Binding to substrate changes shape to transport across

  20. What molecules are transported by channel-mediated facilitated diffusion? • Small lipid insoluble solutes; • Mostly ions selected by size and charge

  21. What molecules are transported by Osmosis? • Water molecules; • Through a specific channel protein-aquaporin or through the lipid bilayer

  22. Facilitated diffusion requires energy. T or F • False

  23. The lipid bilayer consists of hydrophilic heads and hydrophobic tails. T or F • True
