Do animal cells have a cell wall?


Cell wall is present in plants, but absent in animals.

Cell wall

A cell wall is defined as a rigid, external layer that is specifically designed to provide structural support and rigidity. It also keeps the interior components of the cell intact and safe from the external environment.

  • The cell wall’s primary purpose is to provide structural protection and a semi-permeable surface through which molecules can move in and out of the cell.
  • The primary cell wall, secondary cell wall, and middle lamella are the three layers that make up a typical plant cell wall.
  • Prokaryotic cells, such as bacteria, also have a cell wall. Its cell wall, on the other hand, is made up of peptidoglycan, that is made up of sugars and amino acids. Fungi have cell walls, which are made of chitin, a complex carbohydrate.
