endocytosis
Endocytosis is a process which allows a cell to engulf molecules in their entirety and surround those molecules in a membrane. Transport is when small molecules can actively transport through a cellular membrane and come out again.
The movement of molecules across a membrane down the concentration gradient is a passive process.
The process is called hydration. Water molecules surround ions and form a hydration shell, which helps in the dissolution of the ions in water.
A carrier protein helps transport molecules across a cell membrane by binding to specific molecules and changing shape to move them across the membrane.
Water molecules cross the cell membrane through a process called osmosis, which is driven by the concentration gradient of water inside and outside the cell. Aquaporin proteins on the cell membrane facilitate the movement of water molecules into and out of the cell.

The first step in the dissolving process is "The solvent molecules surround the solute particles".
The process whereby water molecules surround ions during the process of dissolving is called hydration. This occurs when water molecules interact with and surround the charged particles of an ionic compound, breaking the ionic bonds and allowing the compound to dissolve in water.
