the cell membrane
Selectively permeable.
semipermeable or selectively permeable.
The selectively permeable phospholipid bilayer (a.k.a plasma membrane) is 'selectively permeable' because it selects which molecules it allows to permeate (pass through).
Cell membranes are indeed selectively permeable.
a dialysis membrane is selectively permeable, it is used in experiments to simulate cellular membranes, and it is permeable to water but not to sucrose.
Plasma (Cell) Membrane
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
no
Cell membrane is elastic and transparent. It can be impermeable, permeable, semi-permeable or selectively permeable. In humans the plasma membrane is selectively permeable that is it allows entry to certain substance.
Cell membranes are selectively permeable while cell walls are semi-selectively permeable. Keep in mind that only low level organisms, like plants, have cell walls.
A mirror is not selectively permeable. The mirror's surface is rigid since it cannot allow any substances to pass through it.
