A cell wall is the wall of a cell in plants bacteria fungi algae and some archaea.

Simple definition of cell wall. Cell walls are present in most prokaryotes except mollicute bacteria in algae fungi and eukaryotes including plants but are absent in animals. The rigid outermost cell layer found in plants and certain algae bacteria and fungi but absent from animal cells. It provides the cell with both structural support and protection and also acts as a filtering mechanism.

A cell wall is a structural layer surrounding some types of cells just outside the cell membrane it can be tough flexible and sometimes rigid. This outer covering is positioned next to the cell membrane plasma membrane in most plant cells fungi bacteria algae and some archaea. 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.

American heritage dictionary of the. The cell wall is the outermost covering of plant cells. A cell wall is a rigid semi permeable protective layer in some cell types.

The cell wall has many important functions in a cell including protection structure and support. 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 cell wall is present only in plants fungi and bacteria.

As mentioned earlier the cell wall is present in all plant cells fungi bacteria algae and some archaea. The cell wall is the outer covering of a cell present adjacent to the cell membrane which is also called the plasma membrane. Cell wall synonyms cell wall pronunciation cell wall translation english dictionary definition of cell wall.

Animal cells do not have cell walls nor do protozoa cell walls protect the cells from damage. This is why it s called the middle lamella even though it is the outermost layer. Animal cells however do not have a cell wall.

The image above represents a plant cell wall. It is also there to make the cell strong to keep its shape and to control the growing of the cell and plant.
