  2. Cell wall - Wikipedia

    en.wikipedia.org/wiki/Cell_wall

    Diagram of the plant cell, with the cell wall in green. Cell walls serve similar purposes in those organisms that possess them. They may give cells rigidity and strength, offering protection against mechanical stress. The chemical composition and mechanical properties of the cell wall are linked with plant cell growth and morphogenesis. [11]

  3. Cell envelope - Wikipedia

    en.wikipedia.org/wiki/Cell_envelope

    The bacterial cell wall differs from that of all other organisms by the presence of peptidoglycan (poly-N-acetylglucosamine and N-acetylmuramic acid), which is located immediately outside of the cytoplasmic membrane. Peptidoglycan is responsible for the rigidity of the bacterial cell wall and for the determination of cell shape. It is ...

  4. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    The structure of peptidoglycan Bacterial cell walls. The cell envelope is composed of the cell membrane and the cell wall.As in other organisms, the bacterial cell wall provides structural integrity to the cell.

  5. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    The cell wall consists of peptidoglycan in bacteria and acts as an additional barrier against exterior forces. It also prevents the cell from expanding and bursting from osmotic pressure due to a hypotonic environment. Some eukaryotic cells (plant cells and fungal cells) also have a cell wall.

  6. Plant cell - Wikipedia

    en.wikipedia.org/wiki/Plant_cell

    Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...

    Re EncycloPetey: "The yellow is the cell wall" - no it's not, the yellow is clearly labeled as the capsule, the cell wall is labeled as the light green layer below the thick yellow capsule layer (this is the second time you've repeated this mistake). So it's not fine; either your claims are wrong or the diagram is mislabeled, and either way ...

  9. Secondary cell wall - Wikipedia

    en.wikipedia.org/wiki/Secondary_cell_wall

    The secondary cell wall is a structure found in many plant cells, located between the primary cell wall and the plasma membrane. The cell starts producing the secondary cell wall after the primary cell wall is complete and the cell has stopped expanding. [ 1 ]
