Diffusion is a physical process that involves the spontaneous movement of molecules from where they are plentiful to where they are scarce.
This process could occur in either directions and is dependent on the direction of the concentration gradient. If for example, there are more water molecules outside the cell, then the water molecules would diffuse into the cell and if there are more water molecules inside the cell, they would diffuse out of the cell.
I both cases, the water molecules have to travel through the cell membrane, which brings us to the next concept: Osmosis - which is the diffusion of molecules along a concentration gradient through a semi-permeable membrane (the cell membrane)

Molecules can pass through the cell membrane of the human cell?
The molecules that can pass through the cell membrane of the human cell include water. Other molecules include fat soluble vitamins.
Water passes through a cell membrane by?
What_is_the_passage_of_water_through_cell_membranes_calledPassage of water through cell membranes occurs through osmosis.
Water moves from tracheid cell to tracheid cell through?
vessel cells
What substance must pass through a cell's membrane for the cell to continue to function?
water and nutrients.
How water molucleus move through the cell membrane doing out mosis?
During osmosis, water molecules move through the cell membrane by passing through microscopic openings in the membrane. The openings are large enough for the water molecules to pass through.
Why does defusion happen?
To let things through the cell membrane
What are the release dates for Defusion 4 Bio-Cell System - 2014?
Defusion 4 Bio-Cell System - 2014 was released on: USA: 31 October 2014 (video premiere)
What is the difference between osmosis and defusion?
Osmosis is the transfer of water through a membrane to have an equilibrium of water particles on each side. Defusion is also the transfer of water through a membrane, but because it is trying to make the concentrations of ions on each side equivilant.
What is going on when cells in a plant root drink water through the cell membrane?
Osmosis
Cells in a plant root drink water through the cell membrane. what process is going on?
Osmosis (endo-osmosis to take water inside plant cell)
What process do plants use to absorb water?
Generally the pull of transpiration (evaporation of water through the leaves) will pull water in from the roots. Adhesion and cohesion also allow the water to move up the xylem of a plant (through capillary action).
What process is going on when cells in a plant root drink in water through the cell membrane?
Osmosis (endo-osmosis to take water inside plant cell)
How can water go through the cell membrane when it is polar?
Because it is a small molecule, water can diffuse through the cell membrane.
What can Water oxygen and carbon dioxide can enter a cell through?
Through the cell membrane.
What can be transported through a cell?
water
What regulates the flow of water through a cell membranes?
concentration of water A concentration of solutes regulates the flow of water through a cell membrane.
Water moves from tracheid cell to trachied cell through?
the Roots.
