Document Summary
Define a cell and list its principal parts. Describe the structure of the plasma (cell) membrane and explain its functional significance. Describe the structure and functions of the following cellular structures: cytoplasm, nucleus, ribosomes, endoplasmic reticulum (er), golgi complex, mitochondria, vaults, lysosomes, perioxisomes, cytoskeleton, centrioles, flagella, and cilia. Cytoplasm = everything between the membrane and the nucleus cytosol = intracellular fluid organelles = subcellular structures with specific functions. Lesson 2 - the plasma membrane and membrane transport. Describe the structure and composition of plasma membrane and different types of cell to cell adhesions. Compare and contrast passive and active cell transport processes. Describe the processes of diffusion, facilitated diffusion, osmosis, and filtration. Define the term tonicity and distinguish between isotonic, hypertonic, and hypotonic solutions. Compare exocytosis and endocytosis for similarities and differences. Controls movement of molecules into and out of cell. Membrane proteins are attached or inserted within lipid bilayer.
