When a cell's membrane is permeable, it means that only certain proteins and other molecules can go in and out of the porous membrane, through protein pumps and other pathways. Some molecules stay inside the cell, while others float outside. Starches, for example, are large molecules that cannot pass through the membrane.
Permeability- being able to be pierced/passed through.
A cell membrane that allows certain particles through but not others e.g. it may let potassium ions through but not have large enough holes to let water molecules through.
The membrane only allows certain chemicals through.
it only allows specific things to enter.
selective permabiltiy
It has selective permeability (allows it to control what comes in and out of the cell) and it isolates the cytoplasm.
The selective permeability of a cells membrane helps the cell to maintain homeostasis because it controls what goes in and out of the cell. This is extremely important for the health of the cell.
plasma membrane
No. Permeability of glycerol through plasma membrane= (approx) 1.9 x 10^-9 m/sec Permeability of water through plasma membrane = 2.0 x 10^-6 m/sec
Selective permeability refers to the fact that the plasma membrane can choose which molecules to let in or out of the cell.

selectively permeable or selective permeability
Selective permeability otherwise known as semipermeable membrane.
It has selective permeability (allows it to control what comes in and out of the cell) and it isolates the cytoplasm.
The plasma membrane regulates what enters/leaves cell through the phospholipid bilayer using selective permeability, by which a membrane allows some substances into the cells while keeping others out. Picture a butterfly net, the holes in the allow knats and other bugs to pass through, while capturing other
