Diagram A correctly shows the movement of materials by osmosis.
- Osmosis can be defined as the net movement of a fluid (e.g., water) across a semipermeable biological membrane.
- Osmosis movement is due to different concentrations of one or more solutes on both sides of the cell membrane.
- Osmosis does not require energy to move substances across the membrane.
In conclusion, Diagram A correctly shows the movement of materials by osmosis.
