The answer is is OSMOSIS the spontaneous net movement of water across a membrane from a region of low concentration to a solution with a high concentration, down a solute concentration gradient.

By active transport often done by integrated proteins embedded in plasma membrane.
Diffusion is the movement of particles from an area of high concentration to an area of lower concentration. Active transport is the movement of substances from lower to higher concentration across a semi permeable membrane that must have a specific protein carrier and cell expenditure of energy.

Diffusion
Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.Explanation:Diffusion is a passive process. It is like when you open a bottle of perfume, soon the whole room will be covered with its smell. From region where the concentration is high, the molecules move to the regions where the concentration is low down the concentration gradient unless equilibrium is reached. Diffusion is the net movement of molecules from the region of higher concentration to region of lower concentration.
No, osmosis is the movement of water particles through a semi-permeable membrane, from a place where there is a high concentration of water, to where there is a lower concentration of water. It can be confusing, because when we talk about solutions we often refer to the concentration of the solute rather than the solvent. For instance, if we have a cell containing cell sap with a high concentration of sugar, and a more dilute solution outside the cell, water will flow into the cell. If you think about the sugar, it might seem that particles are going to the more 'crowded' areas, but the important thing is the concentration of the molecules which are moving, i.e. the water molecules. A dilute solution of sugar has a higher concentration of water than a concentrated one.
Yes
This is called diffusion, but it is a purely statistical process - randomly moving particles have a higher probability of spreading from an area of high concentration to an area of low concentration than the other way around, simply because there are more of them in the area of high concentration.

Diffusion is the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration. This is due to the random movement of the molecules.
active transport
Active transport if you are moving particles to increase the concentration. Or Osmosis if the particles transported are those of the solute to effectively reduce the concentration.
who even knows!
diffusion
the movement of particles from areas of greater concentration to area of lesser concentration.
