1.1.3
1. How does a single cell-the fertilized egg-give rise to a complex, multicellular organism?
By using the process of cell differentiation
2. How does cellular differentiation occur in eukaryotic cells?
3. What role do stem cells play in cell differentiation?
4. How do chemical signals control cellular activities?
Because the signals are like instructions for other cells
1.2.1
1.What is the role of the plasma membrane in maintaining homeostasis?
By blocking out any negative material from entering
2. How does the cell maintain homeostasis through the regulation of:
