Study Guide Overview

This study guide covers tonicity, osmosis, and water potential. It explains how water moves across cell membranes in hypotonic, hypertonic, and isotonic solutions. It also details the process of osmosis and emphasizes the difference between solute and solvent movement. Visual aids are provided for both animal and plant cells.

AP Biology: Osmosis & Water Potential - The Night Before 🚀

Hey! Let's get you prepped for the exam. This guide is designed to be super clear and easy to use, especially when time is tight. We'll cover everything you need to know about tonicity, osmosis, and water potential, with a focus on what's most likely to show up on the test.

Tonicity: Cell's Water Balance ⚖️

Understanding how water moves in and out of cells is crucial. It's all about the concentration of solutes (stuff dissolved in water) inside versus outside t...
