In an experiment, pieces of onion epidermis are placed in three different sucrose concentrations, P, Q and R. The onion pieces are left for an hour and then observed with the low power of a light microscope. Each diagram shows one cell from the epidermis that was placed in each sucrose concentration. What accounts for the appearance of the cells in solution Q?
- AThe concentration of solution Q is equal to the concentration of the solutes in the cell sap.
- BThe cytoplasm has the same concentration of sucrose as solution Q.
- CThe water potential of the cytoplasm is equal to the water potential of the vacuole.
- DThe water potential of the cell sap is equal to the water potential of solution Q.
