Why do cells have to be small?
Greatly simplifies the transport processes involved with supporting the chemical processes going onThe principle purpose of the cell is to act as a container for some particular chemical reaction(s)Products of reaction (waste materials) must be removed from the reaction site, and new reactants must be brought inWhen the cell is small, simple diffusion can move these things across the cell boundary and across the reaction sites (e.gmitochondria.) If the cell were large, then a more elaborate process for performing this transport would be requiredAt a macroscopic scale, the analogous situation would be a factory which has its raw material supplier and waste disposal facility right next door versus a factory in the middle of the state/country which has it's raw material supplier at one end of the state/country and its waste disposal facility at the otherThe latter requires trucks, trains and airplanes in addition to the forklifts and cranes also required by the formerThe name of the game is efficiency, where less is more and making the most of less is the key to success.
