Chapter 3 Review: Cells
Things to focus on:
-The structures of cell organelles and their functions
-The differences between a plant and an animal cell
-The structures of the plasma membrane
-The importance of cell diversity and the functions of each cell based off of their structure
-The different processes of membrane transport
-Diffusion, osmosis, facilitated diffusion, filtration, active transport, endocytosis, exocytosis, phagocytosis, pinocytosis
-Review the concepts of the cell membrane lab
-Study notes, read the chapter, focus on the chapter summaries, review labs/homework!
