Which of the following lacks membrane?

Correct option is C

Correct Answer: (c) Viruses

Explanation:

• Viruses lack a cellular membrane and do not have a cellular structure like plant, animal, or fungal cells.
• They are acellular entities composed of genetic material (DNA or RNA) enclosed in a protein coat called a capsid.
• Some viruses may have an additional lipid envelope derived from the host cell, but they lack their own cellular membrane or organelles.

Other Options:

• Plant cell: Plant cells have a cell membrane and an additional rigid cell wall made of cellulose.
• Fungi cell: Fungi cells have a cell membrane and a cell wall made of chitin.
• Animal cell: Animal cells have a cell membrane but lack a cell wall.
