The diagram labeled C shows the appearance of a plant cell several minutes after it has been placed in a concentrated solution of sugar. Hence the correct option is c.
As the water flees, the vacuole shrinks like a deflated balloon, dragging the cytoplasm with it. This pulls the plasma membrane away from the rigid cell wall, creating a gap you can see in diagram C – that's plasmolysis in action! The once plump grape now resembles a wrinkly raisin, illustrating the dramatic effect of water loss.
This phenomenon isn't just a sad story for our grape-cell. Plasmolysis is a crucial concept in plant science. It explains why plants wilt in droughts, where the soil acts like a hypertonic solution, sucking the water out of their cells. It's also behind the magic of food preservation, where concentrated sugar solutions create hypertonic environments, preventing the growth of bacteria that thrive in water.
So, the next time you bite into a plump grape or see a wilting leaf, remember this tale of the thirsty grape and the invisible battle for water that shapes the lives of plants, all thanks to the sneaky power of osmosis and plasmolysis. Hence the correct option is c.
