Cell membrane of a cell is responsible for the substances
that goes in and out of the cell’s cytoplasm and organelles. It is transports
different materials externally to internally and vice-verse. Hence the cell
membrane is like
1. The wall,
window and door of a house.
2. The
security guard of a certain bank
3. Or the
military sector of a country.
Like these three real-life examples, they regulate and
control the flow of certain entities from outside to inside and vice-versa.
