3.1: Define what prokaryote and eukaryote cells are and give an example of a type of organism for each group. - Prokaryote: "before nucleus"- these are bacteria and cyanobacteria Eukaryotes: "true nucleus"- these are all other cells, including plant and animal cells 3.2: State the symbols used for millimeters, micrometers and nanometers and be able to convert measurements - Millimeters to Micrometers: divide by 1000 Micrometers to Nanometers: divide by 1000 Nanometers to Micromet...

Dynein Correct Answer A class of motor proteins that convert cellular energy to mechanical energy. They allow for migration, propagation, and movement of cells/organelles usually along the microtubules. microtubules Correct Answer A cytoskeletal element found in cilia, flagella, the mitotic spindle, and centrioles. Involved in cell division, cell movement, and axonal trafficking in neurons. Consists of a cylindrical outer structure of helical, polymerized heterodimers of α- and β-tubulin. G...

What is cell theory? - ANSWER It states that the cell is the fundamental structure of all living matter, and that cells can only develop from other existing cells. Why was cell theory not fully developed before the mid-19th century? - ANSWER Before then, microscope magnification was not as powerful, and so scientists were unable to see and identify single cells or cell components. Describe the process of calibrating a microscope. - ANSWER 1. Place the stage micrometer on the stage and alig...
