Answer:
Osmosis
Step-by-step explanation:
The movement of water across the semipermeable membrane is called osmosis.
The semipermeable or selectively permeable membrane allows only certain solutes to pass through the membranes and hinders other solutes. The water level is the same, but the concentration of the solutes is different on both sides of the membrane. So this passive transport of the water occurs to balance the concentration of solutes on both sides of the membrane.
