A spherical bacterial cell has a radius of $3 \mu \mathrm{m}$. The human egg cell has a radius of $100 \mu \mathrm{m}$.
Which statement correctly indicates the cell that is able to more efficiently exchange materials with the external environment and provides a correct explanation?
(A) The egg cell, because it has the smallest surface - to - volume ratio.
(B) The egg cell, because it has the largest surface - to - volume ratio.
(C) The bacterial cell, because it has the smallest surface - to - volume ratio.
(D) The bacterial cell, because it has the largest surface - to - volume ratio.

***D*** ∻Key Concept∻ ⚹Surface-to-volume ratio⚹ ∻Explanation∻ ⚹The bacterial cell, with a smaller radius, has a larger surface-to-volume ratio compared to the human egg cell. This larger ratio allows for more efficient material exchange with the external environment.⚹◊What is the relationship between surface-to-volume ratio and efficiency of material exchange in cells?⍭ Generate me a similar question◊
