Part 1: Post a Response

This week is all about the smallest components of life: atoms, molecules, and cells. In this discussion topic, we concentrate on cells. To begin, watch the Khan Academy video “Introduction to the cell” found at: https://www.youtube.com/watch?v=5KfHxF6Vhps and then address the following questions.

· In the video, the narrator says that we might think that since cells are so small, that they must be simple, but “nothing could be further from the truth.” Give a few examples to illustrate the internal complexity of cells.

· Did anything in this video surprise you, or was it mainly a recap of material you already knew?
