  2. Cellulose - Wikipedia

    en.wikipedia.org/wiki/Cellulose

    Mechanical properties of cellulose in primary plant cell wall are correlated with growth and expansion of plant cells. [17] Live fluorescence microscopy techniques are promising in investigation of the role of cellulose in growing plant cells. [18]

  3. Cell wall - Wikipedia

    en.wikipedia.org/wiki/Cell_wall

    A plant cell wall was first observed and named (simply as a "wall") by Robert Hooke in 1665. [3] However, "the dead excrusion product of the living protoplast" was forgotten, for almost three centuries, being the subject of scientific interest mainly as a resource for industrial processing or in relation to animal or human health.

  4. 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 ...

  5. Secondary cell wall - Wikipedia

    en.wikipedia.org/wiki/Secondary_cell_wall

    Secondary cell walls provide additional protection to cells and rigidity and strength to the larger plant. These walls are constructed of layered sheaths of cellulose microfibrils, wherein the fibers are in parallel within each layer.

  6. Hemicellulose - Wikipedia

    en.wikipedia.org/wiki/Hemicellulose

    In addition, hemicelluloses may be branched polymers, while cellulose is unbranched. Hemicelluloses are embedded in the cell walls of plants, sometimes in chains that form a 'ground' – they bind with pectin to cellulose to form a network of cross-linked fibres.

  7. Wall stress relaxation - Wikipedia

    en.wikipedia.org/wiki/Wall_stress_relaxation

    The primary cell wall of a plant consists of cellulose fibers, hemicellulose, and xyloglucans. [2] This load bearing network is also surrounded by pectins and glycoproteins. Wall stress relaxation is an important factor in cell wall expansion. Wall stress (measured in force per unit area) is created in response to the plant cell's turgor ...

  8. Cellulose synthase (UDP-forming) - Wikipedia

    en.wikipedia.org/wiki/Cellulose_synthase_(UDP...

    Cellulose microfibrils are made on the surface of cell membranes to reinforce cells walls, which has been researched extensively by plant biochemists and cell biologist because 1) they regulate cellular morphogenesis and 2) they serve alongside many other constituents (i.e. lignin, hemicellulose, pectin) in the cell wall as a strong structural support and cell shape. [15]

  9. Ground tissue - Wikipedia

    en.wikipedia.org/wiki/Ground_tissue

    Collenchyma cells are usually living, and have only a thick primary cell wall [6] made up of cellulose and pectin. Cell wall thickness is strongly affected by mechanical stress upon the plant. The walls of collenchyma in shaken plants (to mimic the effects of wind etc.), may be 40–100% thicker than those not shaken.
