Cells: The Smallest Components of Life

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(dot)youtube(dot)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?

*** Question 2---In this week’s discussion you will be exploring energy and how it’s captured, released, and used by all living creatures.
Review the video about the "phytoplankton that brought Earth to life" found at: https://youtu(dot)be/m_43nR11PW8. In this clip, Penny Chisholm discusses a tiny phytoplankton called Prochlorococcus. Based on that video, address the following:
In the video, Dr. Chisholm tells us that Prochlorococcus samples from different environments that are genetically different. Discuss what this tells us about the relationship between organisms and their environments.
What do you think is the most interesting or significant aspect of Prochlorococcus?
