  1. What is life? How are all living things the same, and how are they different?
  2. How do living things maintain relatively constant internal conditions despite significant variation in external environmental conditions?
  3. How does a single‐cell become a complex organism in which different cells have different structures and perform highly specialized functions?
  4. How is light energy from the sun transformed into energy usable by plants, and how do all organisms use stored chemical energy to perform the functions necessary for life (building and breaking down macromolecules, regulating the internal environment, etc.)?
