When a substance wants to enter a cell it goes through the cell membrane in a process called endocytosis.
the cell membrane allows what substance to enter the cells.
ENZYMES
the atoms of the solute(substance getting dissolved) enter the inter-spaces between the atoms or molecules of the solvent .this is how things dissolve, small molecule take space in between the larger molecules and they intermix together. remember dissolving is a physical change not chemical.

osmosis
The molecules of the substance gain thermal energy as a result of which they vibrate more energetically. When the molecules have acquired enough energy they escape from the solid and enter the gaseous phase. Incidentally, there is no requirement for there to be a liquid phase between the solid and gas.
