Question

Cell wall is absent in the cell of
A. Mushroom
B. Moss
C. Fern
D. Mosquito

Answer 1

Hint: Cellular level organization is found in all living organisms. The cell structure is slightly different in all organisms. The basic structure of cells is almost similar in all types of organisms. The cell membrane, cell organs, and nucleus are found in all eukaryotic cells.

Complete answer: In some organisms around cell membranes a dead and rigid wall is found that is called a cell wall. The cell wall is found in bacteria, some protists, fungi, and plants. But animal cells lack a cell wall in their structure.
-The cell wall is made up of polysaccharides and their derivatives. Some substances are deposited on this and make it thicker. The Bacteria cell wall is made up of peptidoglycan (mucopolysaccharide). In Fungi, it is made up of chitin. In plants and algae, cell walls are made up of cellulose and other substances like calcium and magnesium pectate.
In animal cells, no cell wall is found. Mosquito is included in the Insecta class of phylum Arthropoda. But fern and mosses belong to bryophytes in the plant kingdom. Their cell membrane is surrounded by a cell wall. Mushrooms are included in Kingdom Fungi.
Hence, the correct answer is option D.

Note: Cell wall provides mechanical support to cell. This is a rigid and elastic structure. In plant cells, cellulosic microfibrils make cell wall. It maintains the shape of a cell. The cell wall is permeable. It makes contact between two cells by plasmodesmata.
