Document Summary

Compare and contrast prokaryotic and eukaryotic cells. Explain why surface area-to-volume ratios dictate cell size. Label the features of a plasma membrane and describe the function of each component. Explain the functions of the plasma membrane including its role in exocytosis and endocytosis. Compare movement of materials across the plasma membrane by simple diffusion, facilitated diffusion, osmosis, and active transport. Explain the differences between hypertonic, hypotonic, and isotonic solutions and predict the movement of water in or out of a cell in each case. Describe the function and structural features of each of the following organelles: nucleus, endoplasmic reticulum, golgi complex, lysosomes, and mitochondria. Compare and contrast the structure and function of the three fibers that make up the cytoskeleton. Explain in general terms how the food we eat is converted into cellular energy as atp. Describe the role of atp as the energy currency of the cell. All living things are made up of cells.
