The non-living outer-most part of a plant cell.
A structure composed mostly of cellulose and lignin that surrounds the plasma membrane in plants. The cell wall provides structure and helps regulate water intake.
Mechanically strong extracellular matrix deposited by a cell outside its plasma membrane. It is prominent in most plants, bacteria, algae, and fungi. Not present in most animal cells.
this structure is found outside the plasma membrane. Cell walls are found in plant cells, bacterial cells and fungal cells. Each phylum has it's own characteristic chemical composition.
in plant cells, a tough, rigid structure made up of cellulose which is outside of the cell membrane; provides physical support and helps cells resist osmotic pressure.
A specialized, rigid extracellular matrix that lies next to the plasma membrane, protecting a cell and maintaining its shape. It is prominent in most fungi, plants, and prokaryotes, but is not present in most multicellular animals. ( Figures 22-29 and 22-32)
The rigid external covering of a plant cell, composed mainly of cellulose.
a strong membrane outside the plasma membrane present in certain cells, such as bacteria and plants.

('sel 'wol) — The tough, rigid outer covering that surrounds the cell membrane of plant cells. It protects plant cells and helps the plant keep its shape.
Tough wall around plant cells. Helps to support the cell.
A solid shell, made of murein in eubacteria and of a different material in archaebacteria, that surrounds most prokaryotic cells. ~ See Also: Archaebacteria, Eubacteria, Murein.
a thin membrane around the cytoplasm of a cell; controls passage of substances in and out of the cell
a dependent biostructure outside the plasma membrane of the cells of some organisms
a well-defined polymeric matrix located just outside the plasma membrane of a cell
The outer structure of the cell.
outer layer of a plant cell. It is made of cellulose and provides strength.
A rigid boundary consisting of peptidoglycans in prokaryotic cells and cellulose in plant cells. 14, 64
A structure external to the plasma membrane of a plant cell. It provides structure and support.
A rigid structure that surrounds, protects and gives shape to plant, fungi and many bacterial cells. Animal cells do not have cell walls. In plants, the cell wall is the outermost layer of a cell, and is made of cellulose. See cell membrane above
Unique to plant cells, a wall formed of cellulose fibers embedded in a polysaccharide-protein matrix. The primary cell wall is thin and flexible, whereas the secondary cell wall is stronger and more rigid and the primary constituent of wood.
The limiting membrane of a cell
Structure produced by some cells outside their cell membrane; variously composed of chitin, peptidoglycan, or cellulose. PICTURE
multi-layered, sturdy structure composed of cellulose that provides plants and other organisms with their rigidity
Cell walls encompass and support plant cells. They are hard, permeable, and nonliving.
The rigid outermost layer of a plant cell.
outer layer of bacteria exposed to the outside environment - some bacteria do not possess a cell wall
Rigid structure deposited outside the cell membrane. Plants are known for their cell walls of cellulose, as are the green algae and certain protists, while fungi have cell walls of chitin.
Structure found outside the cell membrane in plant cells. Cell walls are absent in animal cells.
A tough outer covering that overlies the plasma membrane of bacteria and plant cells.
the firm nonliving and usually chiefly cellulose wall that encloses and supports most plant cells
a thick, rigid membrane that surrounds a plant cell. This layer of cellulose fiber gives the cell most of its support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.
A cell wall is a fairly rigid layer surrounding a cell located outside of the cell membrane that provides the cell with structural support and protection. They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.
