Question 6Surface-area-to-volume ratios indicate
a chicken egg is one cell thus demonstrating the upper limit for metabolizing cell size.
as cells get larger, their surface area actually decreases.
as cells get larger, their surface area gets larger but at a slower rate than the volume increases.
cells must exceed a certain minimum size.
