nova6 is a very dedly gas that was made in1960
Yes, the cell membrane is selectively permeable, meaning it allows certain substances to pass through while blocking others. This is essential for controlling the movement of molecules in and out of the cell to maintain internal balance.
To let things through the cell membrane
Acids and chemicals
Things can pass in and out through the cell.
They are both semipermeable allowing certain things to pass though membrane and other not to pass through membrane.
Plants and animals are two examples of living things that are eukaryotic. They have their genetic material enclosed within a membrane-bound nucleus and possess other membrane-bound organelles within their cells.
The cell membrane, this is because of the lipids that form it. They allow certain things through such as water during osmosis but block other things creating a need for things like protein pumps.
There are various ways that things can get through the cell membrane. It will depend on the type of particle (size, charge, etc.). Non-polar molecules, such as fatty acids, pass freely through the membrane. Small, uncharged molecules, such as water, also pass freely. Large polar molecules and ions, such as K+ , and macromolecules, such as proteins, so not pass freely through the membrane. They must go through protein channels, pores, etc.
The cell membrane is called as semi-permeable membrane because it allows only certain/selective molecules to pass through it.It mostly allows only solvent molecules to pass.It is sometimes also called as selectively permeable membrane.

Molecules can not pass through the cell membrane, because endocytosis is important for those large molecules that can not pass through the cell membrane!!
