Activity 5: Practice, Reflect, and Review

Practice

• Complete the Chapter 13 quiz.

Reflect

• Go back to your concept map and add new information, make modifications or new connections.
• What questions do you still have about microorganism characteristics and types?
• Add to or modify your concept map to include what you now know about gram positive and gram negative bacteria.

Collaborate

• Access the Microbiology learning community through the WGU portal. The Microbiology Learning Community has a thread for this section, "Bacteria". You can use the tag cloud to locate this thread.
