Name: ______________________________________________________________________ Date: _________________ Block: _____________ Cell Structure and Function Research the following structures and/or organelles found below using a variety of online resources, this does not include your friends or fellow students. In your own words describe the function of each structure. Structures underline should also include a diagram. These functions should go above and beyond the definitions that were given during first year biology. You will need to commit these structures to memory. Every Wednesday you will be assessed on this material by taking a quiz (1st Quarter: Matching, 2nd Quarter: Multiple Choice Questions, and 3rd Quarter: Free Response).
