Detailed explanation-1: -As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell’s needs.
Detailed explanation-2: -Is bigger always better for a cell? Explain. BIGGER IS NOT ALWAYS BETTER. A LARGE SURFACE AREA IS BETTER FOR TRANSPORTING MOLECULES ACROSS THE CELL MEMBRANE, BUT A SMALL VOLUME IS BETTER IN TERMS OF EFFICIENCY OF TRANSPORTING MOLECULES THROUGHOUT THE CELL.
Detailed explanation-3: -Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
Detailed explanation-4: -With smaller cells, more surface area is available for oxygen and nutrients to diffuse in and carbon dioxide to diffuse out of the cell. Thus many small cells can take up oxygen and nutrients and release carbon dioxide much more quickly than one large cell.
Detailed explanation-5: -Small cells are more efficient at exchanging materials than large cells because they have more surface area to work with in relation to their size.
