Energy-free movement of materials through a cell membrane is called passive transport. This process includes diffusion, osmosis, and facilitated diffusion, where molecules move from an area of high concentration to an area of low concentration without the input of energy.
This type of movement is called simple diffusion.
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.

The movement of water and dissolved materials through a cell membrane is called Osmosis.
This sort of membrane is said to be semipermeable.
It's called passive transport for a cell's membrane. (I checked with my science teacher)

The movement of water through diffusion is called osmosis. Osmosis is the process where water molecules move from an area of higher concentration to an area of lower concentration across a semipermeable membrane.
The movement of water through a semipermeable membrane is called osmosis.
