1. Cells, and cellular products, are the units of structure and function in an organism. 2. All cells come from preexisting cells.

… but the cell is extremely dynamic, constantly producing and degrading proteins, replicating its genome for cell division, and exchanging material with the external environment.

 In the video, identify the following organelles:  Nucleus  Nuclear Pore  Rough Endoplasmic Reticulum  Smooth Endoplasmic Reticulum  Golgi Apparatus  Mitochondria

 In the video, identify the following structures:  Actin Filaments  Microtubules  Intermediate Filaments  Motor Proteins  Centrioles  Ribosomes  mRNA  Polypeptides (or proteins)

 Animation created by researchers at Harvard University to depict daily activities of the cell.  Video is to show students that the life of a cell is very dynamic, compared to the static picture shown in the first slide which we associate with the cell.  Hw Hw
