Final Draft is due Dec 9th
Cell Membrane group quiz - Dec 3
Cell Membrane Test - Dec 7 - the test will have a group portion at the beginning where you can collaborate and discuss the written question. After completing the group portion, you will be given time to independently answer some additional written questions and some multiple choice questions.
Cell Membrane Test Learning Outcomes:
- 2.10 The student is able to use representations/models (pictures) to pose scientific questions about the properties of cell membranes and selective permeability based on molecular structure.
- 2.11 The student is able to construct models (drawings) that connect the movement of molecules across membranes with membrane structure and function.
- 2.12 The student is able to use representations/models (pictures) to analyze situations or solve problems qualitatively and quantitatively to investigate whether the movement of molecules across membranes.
- 2.13 The student is able to explain how membranes contribute to cell functions.
- apply knowledge of organic molecules
- including phospholipids, proteins, glycoproteins, glycolipids, carbohydrates, and cholesterol to explain the structure and function of the fluid-mosaic membrane model
- identify the hydrophobic and hydrophilic regions of the phospholipid bilayer
- explain why the cell membrane is described as “selectively permeable”
- describe passive transport processes including diffusion, osmosis, and facilitated transport
- explain factors that affect the rate of diffusion across a cell membrane (e.g., temperature, size of molecule, charge of molecule, concentration gradient, pressure gradient)
- predict the effects of hypertonic, isotonic, and hypotonic environments on osmosis in animal cells
- describe active transport processes including active transport, endocytosis (phagocytosis and pinocytosis), and exocytosis
- compare specific transport processes – including diffusion, osmosis, facilitated transport, active transport, endocytosis, and exocytosis – in terms of
- – concentration gradient
- – use of channel or carrier protein
- – use of energy
- – types/sizes of molecules transported
- devise and analyze an experiment using the scientific method (e.g., to investigate the tonicity of cells)
- differentiate between cells that have a high or low surface area-to-volume ratio
- demonstrate an understanding of the significance of surface area-to-volume ratio in cell size
