to make proteins
Which of the following is a good analogy for the cell membrane?
A house. A house has windows with screens that allow some things in, like the fresh air, but keep other things out, like flies. A house has an address so deliveries come to the right place. Things can be packaged and mailed from a house. A house has doors that lock and can only be opened by the right key.
A school. A school has many classrooms where students learn about different subjects that will help them be successful in life. A school also has a cafeteria where students get nutritious food to fuel them for the day.
A car factory. A car factory has an assembly line where various car parts are assembled to make a vehicle that runs.
