What are two factors that determine whether or not molecules can pass through a selectively permeable membrane?

One factor is the channel of the molecule, without them the ions and polar molecules would not be able to pass across. Another factor is the size of the molecule, they determine how fast it will defuse.

What is a selectively permeable memberane?
A selectively permeable membrane means that it lets some molecules through but others can't get in.
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
How is the membrane permeability?
means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell
Cell membranes that allow certain molecules to pass through while keeping others out are called?
semi permiable I believe, but I'm not 100 percent sure on the spelling selectively permeable
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 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 a selectlively permeable membrane?
The cell membrane is selectively permeable, allowing some molecules to pass through by osmosis
Diffusion of water molecules across a selectively permeable membrane?
it is osmosis
What do you call a cell membrane that allows certain molecules to pass through?
A selectively permeable membrane.
When some molecules go through a membrane faster than others the membrane is what?
selectively permeable
The passive transport of water across a selectively permeable is called?
Osmosis is the movement of water molecules across a selectively permeable membrane.
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
Is it true if the process by which water moves across a selectively permeable membrane is called diffusion?
Diffusion is a physical process. When it is performed through a selectively permeable membrane, it is called osmosis. Thus osmosis is an appropriate word for movement of water molecules through a selectively permeable membrane and not diffusion.
Is a membrane selectively permeable?
Selectively permeable means that only certain substances are able pass through the cell membrane.A selectively permeable membrane is a membrane that only can be permeated by selective things, in other words a surface that lets some molecules in but not others. Like a cell membrane will let water diffuse into it :)
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.
What is a membrane that allows some substances to pass through but excludes others?
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.
