What characteristic makes the cell membrane selectively permeable?
Passive and active transport. Passive transport doesn't require the cell's energy, while active transport does.
What is a selectively permeable memberane?
A selectively permeable membrane means that it lets some molecules through but others can't get in.
What two factors of a molecule determine whether or not cross the membrane?
size and shape. cell membranes are selectively permeable, so only some molecules can get through. (i.e. water can go through, but starch cant) Polarity and size.

What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.

What is a selectively permeable memberane?
A selectively permeable membrane means that it lets some molecules through but others can't get in.
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 effector?
Effector molecules are small molecules that selectively bind to proteins. These molecules also help regulate biological activity.
Diffusion of water molecules across a selectively permeable membrane?
it is osmosis
The passive transport of water across a selectively permeable is called?
Osmosis is the movement of water molecules across a selectively permeable membrane.
What selectively permeable means?
Selectively permeable describes a cell membrane that allows certain ions or molecules to pass through it by means of passive or active transport.
Which term refers to the movement of water molecules through a selectively permable membrane?
diffusion
What can osmosis be described as?
Osmosis is the movement of water molecules across a selectively permeable membrane.
Does the presence of integral proteins allows membranes to be selectively permeable to certain molecules?
yes
