Putting It Together: Prokaryotes

At the beginning of this lesson, we talked about a recent case of a superbug: a strain of Klebsiella that was resistant to all twenty-six of the available antibiotics.

Think about It

Can you guess how this strain of Klebsiella became so resistant?

Remember, prokaryotes represent a broad spectrum of organisms. This video teaches us about the (mostly) single-celled organisms that make up two of the three taxonomic domains of life, and one of the four kingdoms: Archaea, Bacteria, and Protists (which we’ll learn about in the next module). They are by far the most abundant organisms on Earth, and are our oldest, oddest relatives.

Flashcards: Prokaryotes Vocabulary

It is tempting to view different topics as completely separate, but in fact the ideas we cover in this course are often connected to one another. If you don’t retain the vocabulary from module to module, those connections can be missed. As you continue on, remember to come back and review the terms you’ve learned in order to increase your depth of knowledge.
