Which of the following has a cell wall?

i. Animal cell     ii. Plant cell     iii. Virus

Plant cells have a rigid cellulose cell wall that surrounds the cell membrane, providing structural support and protection. Animal cells, on the other hand, lack a cell wall, and their cell membrane serves as the cell's outer boundary.

Viruses, on the other hand, do not have a cellular structure and thus are not considered living cells. They are instead made up of genetic material (DNA or RNA) encased in a protein coat known as a capsid.
