What are some real life examples of a cell membrane?

Answers

Answer 1

Answer: 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.

Answer 2

Answer:

Inorganic membranes are found under the floor tiles of our bathrooms, in our drinking water filters, and in the fuel cells of industrial plants. Structures that require water resistance are also made up of membranes.

These can be found in gardens, underneath roads, and in ponds and reservoirs.

The cell membrane acts as a barrier and gate. It is semi-porous, meaning that some molecules are able to pass through the lipids bilayer, but others are unable to. Small hydrolysis molecules and gases (e.g., oxygen and CO2) pass through membranes quickly.
