Detailed explanation-1: -Cell membranes are semipermeable, which means molecules can move through them. This is pretty important for cells to survive. Osmosis is where solvent molecules (usually water) move from one side of a cell membrane to the other.
Detailed explanation-2: -Cell membranes serve as barriers and gatekeepers. They are semi-permeable, which means that some molecules can diffuse across the lipid bilayer but others cannot.
Detailed explanation-3: -Permeable membranes allow all substances to pass through, and semi-permeable membranes will only allow specific substances to pass through. Plant cell walls are an example of a permeable membrane. Substances such as water, nutrients, and ions easily pass through the cell wall.
Detailed explanation-4: -: partially but not freely or wholly permeable. specifically : permeable to some usually small molecules but not to other usually larger particles.
Detailed explanation-5: -The cell membrane is called selectively permeable as it only allows specific molecules to pass. Only specific molecules like water and gaseous molecules can pass through the cell membrane directly. It stops the flow of other molecules towards the two sides.
