Surface area/volume ratio of bacteria is exceedingly low compared to the same ratio for larger organisms of similar shape.

  • A.True
  • B.False
  • C.May be
  • D.Can't say

Answer: B

Correct answer: False

The opposite is true: because surface area falls with the square of the linear dimension and volume with the cube, a very small cell has an exceedingly high surface-to-volume ratio. That is the central advantage of being small - a large membrane area serving a small cytoplasm allows rapid uptake of nutrients and rapid growth.
