Multicellularity is advantageous chiefly because it permits

  • A.reproduction without any cell division
  • B.organisms to dispense with a genome
  • C.division of labour among specialised cells
  • D.cells to grow far beyond their normal size

Answer: C

Correct answer: division of labour among specialised cells

Once cells need not each do everything, they can specialise, and a nerve cell, a muscle cell and a secretory cell can each be built for one job and be far better at it than any general-purpose cell could be. Multicellularity also allows an organism to exceed the size a single cell can reach, but the specialisation is what makes the size worth having.
