Question

Cell wall is absent in:

Answer 1

Cell wall is composed of cellulose and it is mostly prominent in plant cell.

It provides structural frame work to the cell and provides strength and rigidity to the cell.

Animal cell lacks the cell wall and starts with the plasma membrane.

Nostoc is a cyanobacteria and has a rigid cell wall like other eubacteria.

Mycoplasma fall under eubacteria but they completely lack cell wall. Also, they are the smallest living cells known and can survive without oxygen.
Mycoplasma lacks cell wall around its plasma membrane which makes it resistant towards common antibiotics such as penicillin that target cell wall synthesis.

Aspergillus is a part of Ascomycetes in Kingdom Fungi. Members of Kingdom Fungi have cell walls that are made up of chitin and polysaccharides.

Funaria is a Bryophyte in Kingdom Plantae and as all the members of Kingdom Plantae, it also has cell wall made up of cellulose.

So, the correct answer is option D.
