Which of the following characteristics most limits the efficiency of a cell's material exchange with its environment?
A. Surface-area-to-length ratio
B. Weight-to-volume ratio
C. Surface-area-to-volume ratio
D. Length-to-width ratio
Answer (2)
The efficiency of a cell's material exchange is mainly limited by its surface-area-to-volume ratio . A higher ratio allows for more efficient nutrient and waste exchange. As cell size increases, this ratio decreases, making material exchange more difficult. ;
The efficiency of a cell's material exchange is primarily limited by its surface-area-to-volume ratio. As a cell grows, its volume increases more than its surface area, decreasing the ratio and impacting its ability to exchange materials effectively. Thus, the answer is C. Surface-area-to-volume ratio.
