About Science Prof Online PowerPoint Resources

Science Prof Online (SPO) is a free science education website that provides fully-developed Virtual Science Classrooms, science-related PowerPoints, articles and images. The site is designed to be a helpful resource for students, educators, and anyone interested in learning about science. The SPO Virtual Classrooms offer many educational resources, including practice test questions, review questions, lecture PowerPoints, video tutorials, sample assignments and course syllabi. New materials are continually being developed, so check back frequently, or follow us on Facebook (Science Prof Online) or Twitter (ScienceProfSPO) for updates. Many SPO PowerPoints are available in a variety of formats, such as fully editable PowerPoint files, as well as uneditable versions in smaller file sizes, such as PowerPoint Shows and Portable Document Format (.pdf), for ease of printing. Images used on this resource, and on the SPO website are, wherever possible, credited and linked to their source. Any words underlined and appearing in blue are links that can be clicked on for more information. PowerPoints must be viewed in slide show mode to use the hyperlinks directly. Several helpful links to fun and interactive learning tools are included throughout the PPT and on the Smart Links slide, near the end of each presentation. You must be in slide show mode to utilize hyperlinks and animations.

3 Q: What are the two basic types of cells

Q: What are the two basic types of cells

________________ Single-celled. Reproduce by binary fission (another copy by dividing). No cell nucleus or any other membrane-bound organelles. DNA travels openly around the cell. All bacteria are prokaryotes. ________________ Eu = “true”; karyon = “nucleus” Most organisms that we can see, such as trees, grass, worms, flies, mice, humans, mushrooms and yeast are eukaryotes. Can either be single-celled or multi-celled. Can reproduce in one of several ways (Ex. meiosis, mitosis). Have cell nucleus within containing its DNA. Nucleus most evident distinction between these cell types.

______________

• External appendages from cell membrane. • Aid in locomotion of the cell or movement of materials near cell. • Motility > coordinated sliding movements of microtubules. • Both Prokaryotes & Eukaryotes can have external appendages, but are constructed differently. • Eukaryotes may have flagella or cilia (components of cytoskeleton covered with plasma membrane). • Prokaryotes may have flagella, endoflagella, fimbiae or pili (composed of protenaceous molecules and not covered with plasma membrane).
