A security guard controls who enters and leaves the school, like a cell membrane monitors entry into and out of a cell.

The school floor is the base of the school, which everything else lies upon. It relates to the cytoplasm because the cytoplasm is where all organelles are held within the cell.

The principal directs all things that should be done in school, as the nucleus controls what's in the cell.

The ceilings and beams supports the school, just as a cytoskeleton supports a cell.

The school bus system sends students home and brings them to school, like smooth ER sends it's enzymes across the cell.

The classrooms are where students complete their work and learn. The rough ER is a place where ribosomes do their hardwork.

Students do tasks directed by the teacher and ribosomes get instruction from cell genes.

The senior class is preparing to move on after school and be useful to the world, as Golgi apparatus prepares proteins to export out of the cell.

The school secretary takes notes and delivers them to people who need them. The vesicle transports materials with the cytoplasm.

The generator allows electricity to fill the school in order to continue activities just as the mitochondria fuels the cell for it to continue the activities and produce energy.

The janitor's closet contains materials in order to keep the school running, as a vacuole stores materials that are needed to keep the cell running.

The janitor keeps the school clean. The lysosome makes sure that the cell waste broken down, so it can be reused and clean.

The wall in a school surrounds the school, so everything kept in place and in shape. The cell wall maintains the cell's shape and structure.

The cafeteria is where students and faculty get food in order for them to eat and have energy as the chloroplast converts energy of the sun into chemical energy.
