This 55 slide PowerPoint presentation includes information regarding passive and active transport. This PowerPoint includes easy-to-follow, but detailed descriptions of diffusion, osmosis, hypotonic solutions, hypertonic solutions, isotonic solutions, passive transport, active transport, endocytosis and exocytosis. This PowerPoint also includes many diagrams and pictures to help ensure student understanding. I have used this PowerPoint with my grade 11/12 Biology class. This is a lengthy PowerPoint, with awesome information. I usually deliver this PowerPoint in at least two lessons. Feel free to download and edit this PowerPoint.
