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.

Both plant cells and animal cells share characteristics such as nucleus, cytoplasm and a cell membrane. The nucleus controls what goes in and out of the cell, the cytoplasm is where cell activity and chemical reactions occur and the cell membrane holds the cell together.
