Cell wall is absent in

  1. Mycoplasma
  2. Nostoc
  3. Aspergillus
  4. Funaria.

Answer

(1) Mycoplasma

Solution

As per NCERT, mycoplasma are organisms that completely lack a cell wall; they are the smallest living cells known and can survive without oxygen.

∵ Nostoc (cyanobacterium) has a cell wall, Aspergillus has a chitin wall and Funaria (moss) has a cellulose wall, they are not the answer.
