Study Guide Semester 1 Final (Part 2) Name Cell Structure and Function The test on Cell Structure and Function is closed note, open brain . To prepare for this test, review the labs and activities, readings, notes, and returned work. Terms to understand, identify in an image, and be able to apply to a variety of problems. Quantitative Observations Qualitative Observations Solute Solvent Solution Hypertonic Hypotonic Isotonic Diffusion Osmosis Concentration Gradient Cell Membrane Selectively Permeable Semi-permeable Compartment Internal External Cell wall Cell membrane Nucleus Nucleolus Nucleoid Region Ribosome Endoplasmic Reticulum Golgi Bodies Vacuoles Lysosome Cytoplasm Cytoskeleton Chromosomes/DNA Chloroplast Organelle Passive Transport Facilitated Diffusion Simple Diffusion Active Transport Energy ATP Protein Transport Phospholipid Bilayer Hydrophilic/Polar Hydrophobic/Nonpolar Solubility Concentration Lipid Channel Protein Carrier Protein Transport Protein Review Tasks: COMPLETE each task in your journal (or simply do the task) and check each box when you have completed the task. Review/re-read journal entries pertinent to the cell unit. These include all handouts and readings. Explain the difference between qualitative and quantitative observations. Given a cell in a type of solution, explain how water moves and why it moves in that direction (hyper/hypo/isotonic). Draw, label, and describe the functions of components of essential structures within cells. Create an analogy to describe how the cell parts function together as a system. Describe the structure of the cell membrane and how the membrane regulates the flow of material into or out of the cell. Describe various methods of transport across cell membranes. Show how they are similar and how they are different (Venn Diagram) Compare and contrast facilitated diffusion and diffusion. Compare and contrast active transport and diffusion. List molecules that may have difficulty crossing the cell membrane and explain why they would. Be able to infer what could happen to the cell if various organelles malfunctioned. Be able to analyze data for information relating to cell behavior in different solutions. Connect at least 3 words (above) together into one sentence that explains something having to do with cell structure, function, or interaction with its environment. Examples: active, molecule, gradient; diffusion, osmosis, concentration gradient; Golgi Bodies, ribosomes, cytoplasm; non-polar, phospholipid, transport. Try it! Visit the calendar/website and go through the review Jeopardy! when it is posted (usually the night before the test). Re-read a chapter in your summer reading book so you can connect ideas discussed in the story to our cell unit. Draw the following: A cell in a hypertonic environment. Label what is hypertonic/hypotonic A cell in a hypotonic environment. Label what is hypertonic/hypotonic A cell in an isotonic environment. Label what is hypertonic/hypotonic. 1. 2. 3. 4. 5. 6. 7. Name the 2 labeled parts. Draw the diffusion of carbon dioxide out of the cell. Draw active transport of sugar into the cell. Active transport moves from _________________ to __________________ and requires _________________ from the cell. Facilitated diffusion moves from _______________ to ___________________ and requires _______________ from the cell. Simple diffusion moves from __________________ to __________________ and requires ________________ from the cell. Osmosis is ____________________ and moves from ________ to ___________ and requires _____________ from the cell. Label the cell parts. Match the description to the cell membrane part. (They may be used more than once.) 13. This area is hydrophobic 14. This part helps move molecules through the cell membrane 15. This area is hydrophilic 16. This is a protein 17. This is made of lipids 18. This is made of a phosphate 19. Explain why the cell membrane is described as a bilayer: In the diagram below, the cell membranes are impermeable to solutes, the concentrations of which are indicated (in the cell vs. outside of the cell). Only the solvent can pass through the membrane. 20. Draw arrows to show the direction of water movement. 21. Predict what will happen to each cell above. Write the answer in the spaces below. 22. Compare Active transport and Passive transport using the T chart below: Place the following terms on the T chart: Facilitated diffusion, Simple diffusion, Osmosis, energy, protein, high concentration to low concentration, low concentration to high concentration, membrane required, ATP used ACTIVE TRANSPORT PASSIVE TRANSPORT
