Easy definition of cell wall. A major function of the cell wall is to give the cell strength and structure and to filter molecules that pass in and out of the cell. Animal cells do not have cell walls nor do protozoa cell walls protect the cells from damage. Plant cell walls are three layered structures with a middle lamella primary cell wall and secondary cell wall the middle lamella is the outermost layer and helps with cell to cell junctions while holding adjacent cells together in other words it sits between and holds together the cell walls of two cells.

The rigid outermost cell layer found in plants and certain algae bacteria and fungi but absent from animal cells. Cell wall definition the definite boundary or wall that is part of the outer structure of certain cells as a plant cell. This is why it s called the middle lamella even though it is the outermost layer.

The cell wall is the protective semi permeable outer layer of a plant cell. It is also there to make the cell strong to keep its shape and to control the growing of the cell and plant. Cell walls are present in most prokaryotes except mollicute bacteria in algae fungi and eukaryotes including plants but are absent in animals.

A cell wall is an outer layer surrounding certain cells that is outside of the cell membrane all cells have cell membranes but generally only plants fungi algae most bacteria and archaea have cells with cell walls the cell wall provides strength and structural support to the cell and can control to some extent what types and concentrations of molecules enter and.
