1. A plant cell is placed in a dilute sugar solution. Which process allows water to enter the cell through its selectively permeable membrane?
  1. Osmosis
  2. Active transport
  3. Plasmolysis
  4. Translocation

Answer: A. Osmosis

Osmosis is the net movement of water through a selectively permeable membrane from a more dilute solution to a more concentrated one.
