Amoeba is called naked because:

  • A.It is single celled
  • B.It has a delicate plasma membrane
  • C.It is uninucleated
  • D.It has all of these

Answer: B

Correct answer: It has a delicate plasma membrane

Naked here means unprotected: the amoeba has only its thin plasma membrane, with no pellicle, test or shell over it. That is precisely what allows the cell to change shape freely and put out pseudopodia, and it is the feature distinguishing the naked amoebae from the shelled forms such as Arcella and Difflugia.
