Question

Is the cell an open or closed system? Explain youranswer using at least one example of a cellorganelle and its function

Answer 1

The cell is an open system. The cell membrane could help us to clarify this. The cell membrane is semipermeable, that is, it allows the entrance

of certain molecules, usually small molecules. Nevertheless it has strategies to allow the entrance of bigger molecules, like its recognition with

its membrane receptors. With these features, the cell interacts actively with its environment, showing it is an open system.
