Basic Cell Functions of mobiles: Basic Cell Functions Cells have evolved to contain many intricate structures inside of its membrane. Many of these structures serve specific purposes. This interconnected network of structures inside of a cell can be compared to the system of gears inside of a simple machine. Just as the gears have to cooperate among themselves to ensure the machine's proper function, the internal organelles of a cell have to interact to ensure the cell's ultimate survival. There are several main functions that the cell has to carry out: molecule transport, reproduction, and energy conversion. Please click on the following to learn more about the various functions.
