Most bacteria have an optimal surface area-to-volume ratio (SA/V) that balances growth, available nutrients, and cellular components. A sphere-shaped bacterium and a rod-shaped bacterium have the same volume, but the surface area of the sphere-shaped bacterium is 4.6 µm2 and that of the rod-shaped bacterium is 0.8 µm2.
Which statement compares the nutrient diffusion of the bacteria?
It will be the same in the sphere-shaped and rod-shaped bacteria since both have similar SA/V ratios.
It will be slower in the sphere-shaped bacterium since it has a higher SA/V ratio.
It will be faster in the sphere-shaped bacterium since it has a higher SA/V ratio.
It will be faster in the sphere-shaped bacterium since it has a lower SA/V ratio.
