Of course, it's unlikely anything like grey goo will happen. Why not?

Could yeast cells (or self-reproducing robots) go on reproducing themselves indefinitely?

What, if anything, limits the total number of cells or robots that can be built?

Write a short fiction story to illustrate rapid growth and then death of a large population of robots, single-celled organisms, or some other kind of machine or creature.

In your response, be sure to include:

• Why or how your fast-growing population reproduces
• What four things each individual needs to be able to do
• At least one way a fast-growing population can be stopped
• Some of the focus words:

cell • divide • multiply • fungus • individual • reproduction • separate • microscopic • exponential
