Facilitator QuestionsEveryone knows that cells are complex, but how could you measure how complex they really are? How could you compare the complexity of a cell with that of some other structure? Why are cells so small? Why do unicellular organisms grow and divide whenever they can? Wouldn’t it be simpler just to differentiate into a stable form and stay in one place? Why is the cell growth and division cycle in multicellular orgnanisms regulated? What properties would you want a microtubule to have to accomplish the jobs it performs during mitosis? Do you see advantages for a cell in having its spindle form inside the nucleus, rather than in the cytoplasm? How about having the spindle in the cytoplasm and the chromosome in the nucleus? How does a cell know when to start anaphase? If you were designing such a system, what properties would you give it, and how would you make it work? What time in the cell cycle is most suitable for the decision to start the division process?
