Final answer:
Cells have a higher surface area to volume ratio to support their increasing volume. They achieve this by developing organelles, increasing surface area through folding of the cell membrane, or by becoming flat or thin and elongated.
Step-by-step explanation:
Cells have a higher surface area to volume ratio to support their increasing volume and maintain normal cell processes. As cells increase in size, their surface area to volume ratio decreases. This is because the surface area increases as the square of the radius, while the volume increases as the cube of the radius.
To achieve a higher surface area to volume ratio, cells may adapt by developing organelles that perform specific tasks, increasing surface area through folding of the cell membrane, or by becoming flat or thin and elongated. These adaptations lead to the development of more sophisticated cells called eukaryotic cells.
