Cellular Structure and Transport Chapter 4 - Intro and section 1 - Explain the significance of compartmentalization of materials in a cell - Why is a cell’s limited? Explain what happens to the surface to volume ration as a cell grows as well as its effect on the viability of the cell.
Chapter 4 - Intro and section 1 - Compare and contrast the pros and cons of light and electron microscopy - how can we chemically analyze the structures of a cell - Compare and contrast prokaryotic and eukaryotic cells in terms of size, structure and complexity
Chapter 4 - Intro and section 1 - Compare and contrast prokaryotic and eukaryotic cells in terms of size, structure and complexity
Chapter 4 - section 5 - Describe the structure of the cell wall for plants and bacteria including: structural composition Functions mechanisms by which molecules move through it
Chapter Discuss the location and role each of the following play in the plasma membrane - phospholipids - Integral, peripheral, transmembrane proteins - Cholesterol - glycolipids/glycoproteins - Be able to relate the chemical composition of each of the above to their location in the membrane
Chapter Differentiate between passive and active transport in terms of energy requirements and concentration gradient - What criteria determine whether a molecule can pass through the phospholipid bilayer using simple diffusion? - How does facilitated diffusion differ? Provide several examples.
Chapter differentiate between each of the following: channel protein carrier protein voltage-gated channel ligand gated channel
Chapter 5.2 and Chapter In what ways can water move across the membrane? - What do the terms hypertonic, hypotonic and isotonic mean and how do they relate to the movement of water? -How is the movement of water influenced by more than solute concentration in plants? -Turgor pressure? Water potential? - How do transpiration and water potential work together to make sure water moves up the xylem of a plant?
Chapter How does active transport differ? - under what circumstances would a cell need to use active transport to move a substance? - describe how the sodium potassium pump works
Chapter Bulk transport – how do cells use vesicles to move large quantities in and out of the cell phagocytosis pinocytosis receptor mediated endocytosis
