Today we're going to watch a video that fits in well with the cells assignments you've done so far.

Watch this video, writing down three things that you didn't know about the cell before as you do.
If you finish that, try this activity. It's related to the microbiology stuff we've been doing. How many ways are there that pathogens (disease causing organisms) can be spread?

Assignments and microbiology in industries

Today we'll either be finishing (and hopefully printing) our assignments, or working on the question below.

1. Explain how fermentation occurs and what the chemical reaction for it is:
2. What industrial uses are there for microbes? List three different ways organisms can be used:
3. For the uses listed above, briefly summarize what role the microbes play and what their requirements are - nutrition, conditions etc. You may need to find some more information to complete this task.
4. Watch this video. Why would using aseptic technique be important in cheese production?

5. Explain what pasteurization is. Why would it be important for this to occur?
