 * __**Must Knows**__  ([|Click Here For Powerpoint]!)  ||  __**Key Vocabulary**__  ||
 * **1. Students will be able to describe how light and electron microscopes function as well as the use of the Metric system when using a microscope.**
 * a**. Microscopes enable biologists to examine the details of cell structure and to understand how organisms function.
 * b.** Scientists use the metric system when measuring objects.
 * c.** Light microscopes have a low magnification and can be used to examine living cells.
 * d.** Electron microscopes have a high magnification but cannot be used to examine living cells.
 * e.** The Scanning Tunneling Microscope uses a computer to generate a three dimensional image of an object.
 * 2. Students will be able to explain the major features of a cell in regards to prokaryotes vs eukaryotes and the cell theory.**
 * a.** The cell theory has three parts. ([|Click Here For Video]!)
 * b.** Small cells function better than large cells due to having a higher surface area to volume ratio compared to large cells.
 * c.** All cells have a cell membrane, cytoplasm, ribosome’s and DNA.
 * d.** Prokaryotes lack internal compartments. ([|Click Here For Video]!)
 * e.** Eukaryotes have a nucleus and other organelles as well as a exoskeleton of microscopic protein fibers. ([|Click Here For Video]!)
 * f.** The lipid Bilayer of a cell membrane is made of a double layer of phospholipid molecules.
 * g.** Proteins in cell membranes include enzymes, receptor proteins, transport proteins, and cell surface markers.
 * 3. Students will be able to summarize and describe the characteristics of a cells organelles.** ([|Click Here For Video]!)
 * a.** The nucleus of a eukaryote directs the cells activities and stores DNA. ([|Click Here For Video]!)
 * b.** In eukaryotes, an internal membrane system produces, packages and distributes proteins. ([|Click Here For Video]!)
 * c.** Mitochondria harvest energy from organic compounds to ATP. ([|Click Here For Video]!)
 * d.** Lysosomes digest and recycle a cell’s used components. ([|Click Here For Video]!)
 * e.** Plant cells have structures that animal cells lack: a cell wall, chloroplasts and a central vacuole. ([|Click Here For Video]!) || * Light microscope
