This week, we delved deeper into organelles. We learned about phospholipids, the fluid mosaic model, and how organelles relate to one another in the cell. Diving into the fluid mosaic model, we learned how cells cross it, using diffusion or osmosis. The ways are passive transport (using diffusion or facilitated diffusion) or active transport. Molecules use different types depending on the type of molecule they are. Then, looking at solute concentration, we learned about hypertonic, isotonic, and hypotonic cells. The cell changes depending on the solute concentration. Can’t wait to learn more in science!
