Of the two cells represented in the figure, which would likely be more efficient at exchanging substances with the surrounding environment?
Understand the Problem
The question is asking which of the two cell models, Cell A or Cell B, would be more efficient in exchanging substances based on their surface-area-to-volume ratio. To determine this, we need to calculate the surface area and volume of each cell and compare their ratios.
Answer
Cell A, because it has the larger surface-area-to-volume ratio.
The final answer is Cell A, because it has the larger surface-area-to-volume ratio.
Answer for screen readers
The final answer is Cell A, because it has the larger surface-area-to-volume ratio.
More Information
A cell with a larger surface-area-to-volume ratio can exchange substances more efficiently with its environment due to its relatively greater surface area compared to its volume.
Tips
A common mistake is miscalculating the surface area or volume which can lead to incorrect surface-area-to-volume ratios.
