Because they are to big and move to slow

When the molecules on both sides of a cell membrane are in equilibrium what will the molecules do?
If the concentration of molecules on both sides of a membrane is the same, nothing will happen to the molecules. Osmosis only occurs when there is an imbalance of the molecules across the cell membrane.
What part of the cell membrane attracts water molecules?
the side with the oxygens (the polar side)
When will water and solutes stop moving across a membrane?
Particles in a given medium stop moving across the membrane during diffusion when a state of equilibrium is reached, that is when the number of particles on either side of the membrane equalizes.
What occurs when molecules ATP to pump molecules from one side of a membrane to the other?
ATP molecules release their third phosphate group in the reaction ATP --> ADP + P + Energy. The energy stored between the second and third phosphate groups is released and used by the cell to do work, such as pumping molecules across the cell membrane.
How do glucose molecules cross a plasma membrane on the apical side of epithelial cells?
secondary active transport
The side from which more water molecules cross the semipermeable membrane?
The pure solvent side is the side from which more water molecules cross the semipermeable membrane.

What is the diffusion of water molecule through a selectively permeable membrane?
It's called osmosis. A selectively permeable membrane will only allow certain molecules to pass trough. To illustrate: If you have a high concentration of sugar molecules on one side of the membrane, no sugar on the other side, and the sugar molecules are too big to pass trough the membrane. If this is the case, then water molecules will diffuse over to the side of the membrane with a high sugar concentration. This happens because the molecules try to distribute themselves evenly in the solution. The water molecules move because the sugar molecules can't.
Why did the number of the water molecules on each side of the membrane change where as the number of sugar molecules stayed the same?
The membrane is permeable to water but not to sugar.
What are the benefits of reverse osmosis systems in purifying water?
Reverse osmosis is a membrane technical filtration method that removes many types of large molecules and ions from solutions by applying pressure to the solution when it is on one side of a selective membrane.
What is it called when the concentration of water molecules is the same on each side of the cell membrane?
Equilibrium
What is it called when the concentration of water molecules is the same on each side of cell membrane?
Equilibrium
How does reversibility work?
Reverse osmosis filters certain types of molecules and ions by applying pressure on one side of the membrane. Reverse osmosis works by introducing a large amount of pressure to a solution to remove large molecules and/or ions completely. This process is similar to other osmosis exercises.

it is called diffusion
