A CEll Is Like A High School
BY Rhema Bauer
Just as the Administrative assistant controls what enters and leaves the school, so the plasma membrane regulates what leaves and enters the cell.
Just as the princible directs all operations that go on in the school, so the nucleus and DNA controls all cell activities and what proteins will be made.
Just as the school floor holds all the desks and every thing thats on it, so the cytoplasm is were all the organelles and activities are found.
Just as the cafeteria kitchen is the place were the workers do their job making food, so the ER is the place were the ribosomes do their job of assemabaling proteins.
Just as the janitors clean up all the trash around the school and recycles the things that can still be used, so the so the lysosomes break down the cell waste so the differant parts can be reused.
Just as the support beams, walls, ceilings, foors, bricks, and cement support the school building, so the cytoskeleton supports and maintains the shape of the cell.
Just like lunch provides the students with energy to do there work, so the mitochondria are the source of ATP that is used for energy in cell processes.
Just as composting breaks down garbege from the students in the school, so the peroxisomes break down hazardous material such as hydrogen peroxide.
Just as the storage closets in the classrooms store material, so the smoothe ER (edoplasmic reticulum) stores steroids and ions.
Just as the teacher directs the students into the auditorium for an assembly, so the necleolous directs the assembly of proteins with in the cell necleus.
Just as the buses drive kids to and from school, so the centrosome is were microtubes carry out transportation.
