Which Statement Best Describes the Relationship Between Cell Size (Surface

question 2

Multiple Choice

Which statement best describes the relationship between cell size (surface area,volume,and average width or radius) and cell function?

• A) Bigger cells have more surface area, more volume, more storage capacity, and are adaptively superior in many ways because of their greater size.
• B) Spherical cells function best because they have a more favorable surface area : volume ratio, which explains why red blood cells and most bacteria are spherical.
• C) The rate of increase of volume exceeds that of surface area, causing membrane transport of nutrients and waste to become progressively inefficient as cell size increases.
• D) Since each feature is determined geometrically, the ratios for any two measurements and cell function capabilities remains constant regardless of overall cell size.
