It is based on the structure of the cell membrane, which has proteins and lipids in it that make some substances impermeable to the membrane, often based on slight electrical charges and sometimes by size of the molecule or other chemical properties.
Some substances require an enzyme or hormone to cross the barrier of the cell membrane, such as binding sites on cell membranes that will not allow glucose into the cell unless insulin binds with the sites, which forms a chemical bridge to allow glucose molecules to pass through the cell membrane into the cell. Without the insulin, the cell membrane is impermeable to glucose.
The cell membrane is the organelle that is selectively permeable.
Plant cells have selectively permeable cell walls and animal cells have selectively permeable cell membranes
it is the plasma membrane.
the fluid mosaic model
the cell membrane
Selectively permeable.
A selectively permeable membrane means that it lets some molecules through but others can't get in.
nope
A mirror is not selectively permeable. The mirror's surface is rigid since it cannot allow any substances to pass through it.
The plasma membrane is selectively permeable because it needs to allow certain things in and certain things out.The plasma membrane is a selectively permeable membrane as it allows the entry and exit of some selected substances only.

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.
A selectively permeable membrane means that it lets some molecules through but others can't get in.
Mitochondria is double membraned!It is known as power house of cell it contain enzymes for production of energy by respiration.
