<span>The plant cell was placed in a hypertonic solution. Due to its higher concentration of solutes and a net movement of water outside a hypertonic solution causes the cell to shrink. In other words, when a plant cell is placed in hypertonic solution the water from the cell will be forced out of the cell in an attempt to balance itself. This is known as plasmolysis.</span>
The endoplasmic reticulum serves many general functions, including the folding of protein molecules in sacs called cisternae and the transport of synthesized proteins in vesicles to the Golgi apparatus.
