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.

Cells have selectively what membranes?
Selectively permeable.
What is a selectively permeable memberane?
A selectively permeable membrane means that it lets some molecules through but others can't get in.
Does selectively permeable and semi permeable mean the same thing?
nope
Is a mirror selectively permeable?
A mirror is not selectively permeable. The mirror's surface is rigid since it cannot allow any substances to pass through it.
Why is the plasma membrane selectively permeable?
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.
What part of the cell is descibe as selectively permeable?
the cell membrane
What part of the is describe as selectively permeable?
the fluid mosaic model
Cells have selectively what?
Selectively permeable.
Cells have selectively what membranes?
Selectively permeable.
What is definition of 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).
What is the relationship between cell membrane and selectively permeable?
Cell membranes are indeed selectively permeable.
How is dialysis membrane 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.
What is a selectively permeable memberane?
A selectively permeable membrane means that it lets some molecules through but others can't get in.
What organelle has a double layer of phospholipids that is selectively permeable?
Mitochondria is double membraned!It is known as power house of cell it contain enzymes for production of energy by respiration.
Selectively permeable part of the cell that controls what enters and exits the cell?
Plasma (Cell) Membrane
Does selectively permeable and semi permeable mean the same thing?
nope
Does the membrane of a cell is selectively permeable?
no
