Chapter 11 - Cell to Cell Communication
Watch Here (Streamed) - You can watch full screen. The video quality is just OK but it is worth it. It will REALLY help you understand cell signaling.
You only need to watch the first 51 minutes. The rest is question and answer time.
When you are finished, look below the video for your assignment.
If you are having trouble streaming the video live, you can download the entire thing and watch it from your computer. To do that click on one of the following file formats. They are HUGE so hit download and walk away for a while.
.mp4 Version- should be compatable with iTunes and iPod / iPhone
Divx version - (780 MB) should be compatable with other media software.
After you watch the video, answer each of the following questions. They have to be a minimum of 1 paragraph (5 sentances) each.
- Describe the symbiotic relationship between the Squid and V. fischerii. What role does each perform? What is the benefit to each?
- Explain the mechanism of quorum sensing as performed by V, fischerii. How does that mechanism allow it to bioluminesce only at night?
- Explain the difference between the mechanisms that allow intra-species communication (communication with siblings) versus interspecies communication (communication with others). How do these mechanisms benefit pathogenic, disease causing organisms?
