I’m working on a Biology question and need guidance to help me study.
I.
Review the video about the “phytoplankton that brought Earth to life” found at: https://youtu.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?
II.
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?
