This is a PowerPoint presenation for an introduction to cells. It covers the first to discover cells (Hooke and Leeuwenhoek), the cell theory, cell size, basic parts of all cells (membrane, nucleus, cytoplasm, organelles), and the two types of cells (prokaryotic and eukaryotic). The presenation includes review questions and links to videos. It takes me 2 or 3 days to complete this PowerPoint. Included in the notes sections are ideas for discussion, answers to review questions, and descriptions of the links.
