Organelles in a cell and what they do

Summary

This video, titled "A Tour of a Cell", is just what it sounds like, a tour of a cell. At the beginning of the video he explains why cells are small and says that its because that if a cell is smaller then when material is going in and leaving the cell it takes significantly less energy than say if the cell was the size of someone's hand. However, its not infinitely small because the organelles in the cell have to fit in their. The video creator then goes through the different types of microscopes, optical (light), scanning electron microscopes (SEM), and transmission electron microscopes (TEM) and explains how they work (1:50). Then he explains how prokaryotic and eukaryotic cells differ (4:03). After that he starts to go through the parts of a eukaryotic cell (5:30). He explains what and how the nucleolus (5:35), nucleus (6:35), ribosomes (7:28), vesicles (7:58), rough ER (8:17), golgi body (8:56), cytoskeleton (9:33), smooth ER (10:36), mitochondria (11:00), vacuoles (11:33), cytosol (12:03) (we didn't learn this), lysosomes (12:19) and centrioles (13:00) work.

Relevance to Class

This video is relevant to our biology class because in class we have had a discussion about how a cell works and the parts of a eukaryotic cell and how they work. We had an outline for homework in the textbook and there were several chapters detailing what every organelle in a cell was and what they did. In class we went over the differences between a eukaryotic and a prokaryotic cell. Also, we recently had a microscope lab and we learned about the parts of a light microscope.
