Unit 6 Objectives
Movement into and out of cells Chapter 5: sections 5.1 – 5.9
Describe the function of the various membrane proteins: integrin, glycoproteins, transport proteins, enzymes, receptors
Describe the movement of materials across membrane
a. Passive transport (describe in terms of concentration of molecules and energy)
b. Diffusion (describe in terms of concentration of molecules and energy)
c. Facilitated diffusion (describe in terms of concentration of molecules and energy and why this is different from
simple diffusion above)
d. Active transport (describe in terms of concentration of molecules and energy)
e. Exocytosis/endocytosis (what is happening?)
f. Explain receptor mediated endocytosis and give an example of something that is taken into the cell in this way.
3. What materials can pass through the phospholipids? through proteins?
4. Which have to pass by exocytosis/endocytosis?
5. Describe the concentration of solutes in Hypertonic, hypotonic, isotonic solutions.
6. If a cell is placed into each to the types of solutions above, where does the water move (into the cell out of the cell) and
what happens to the size of the cell?
7. What type of cells would have turgor pressure? Explain
Lab: Compare two solutions
Cellular Reproduction
Chapter 8
1. Explain what is meant by the cell cycle.
2. Name the 2 main parts of the cell cycle
3. describe what is happening in the 3 phases of interphase
4. Describe the structure of a nonduplicated chromosome and a duplicated chromosome
5. Distinguish between chromatin and chromosomes
6. Explain the process of binary fission and what type of organism perform this
7. List the phases of mitosis in the order that they occur
8. Describe what is happening in each stage of mitosis. Be able to identify from a diagram
9. explain what occurs during cytokinesis and distinguish it from mitosis
10. Explain how cytokinesis differs in plant and animal cells
11. Distinguish between chromosomes, chromatids, centromere, centriole, centrosome
12. Explain what growth factors are and their role in the cell cycle
13. Explain how progress of a cell through the cell cycle is controlled
14. Describe what can result if normal controls of the cell cycle are not working
15. What are 3 reasons a cell would need to divide
16. Distinguish between somatic cells and gametes
17. Distinguish between haploid and diploid. Give specific examples of cells that are each
18. What happens during fertilization?
19. What is the haploid and diploid number for humans
20. describe homologous chromosomes
21. stages of meiosis
a. identify from diagram
b. describe what is happening to chromosomes/nucleus/spindle in each stage
c. when do cells become haploid?
d. Types of cells produced
e. Why important in sexually reproducing organisms
22. 3 ways genetic diversity is increased in sexually reproducing organisms
23. what is nondisjunction?
a. What are results if it happens in meiosis I?
b. What about if it happens in meiosis II?
c. What disorder can be caused by this?
24. Be able to contrast mitosis and meiosis
25. If given a cell with a diploid number of 8, be able to tell from a diagram if the cell is undergoing mitosis or meiosis
Activities/labs: Mitosis under the Microscope, modeling mitosis, extending meiosis
