This powerpoint can be shown in one or two parts. It discusses the characteristics of life, brief history on microscope and cell discovery, eukaryotic and prokaryotic cells, animal and plant cells, cell organelles, diffusion, and osmosis. Filled with pictures! Background color is gray, but can easily be changed to any color you like. Enjoy! I have also posted a "student notes" to go along with this; a simplified powerpoint that can be printed out and distributed to students as handouts. They can follow along copy the notes directly from the powerpoint.
