Eighth graders have been hard at work developing models of real life places to serve as metaphors for cells. In this example, Central Park serves as the metaphor:
- The Jackie Kennedy Onassis Reservoir serves as the cell's central vacuole.
- The police station is the cell membrane because it protects the inner workings of the cell.
- The park rules are the cell wall because it lets certain things in and out of the cell.
- The Arsenal building that houses the park commissioners and rangers is the nucleus because it houses DNA and RNA.
