Answer :
The Cell membrane regulates diffusion, in plants and animal cells.
What is a Cell Membrane?
- Every biological cell has a thin membrane that separates it from the rest of the environment this membrane is known as a cell membrane.
- Cell membranes is made of lipids and proteins.
- The cell membrane's chemical nature makes it extremely flexible, making it a perfect border for quickly growing and dividing cells.
- Cell membrane is a semi-permeable membrane.
Cell membrane does not produce enzymes.
Hence, the option (1) is incorrect.
Cell membrane cannot control reproduction.
Hence, option (2) is incorrect.
The main constituents of cell membrane is lipids and proteins, not sugars.
Hence, option (3) is incorrect.
Cell membrane regulates diffusion, because the cell membrane contains the semi-permeable membrane which allows only lipids and certain small molecules in the cell.
Hence, option (4) is correct.
Therefore, the Cell membrane regulates diffusion, in both plants and animal cells.
