  2. Reticular fiber - Wikipedia

    en.wikipedia.org/wiki/Reticular_fiber

    Reticular fibers, reticular fibres or reticulin is a type of fiber in connective tissue [1] composed of type III collagen secreted by reticular cells. [2] They are mainly composed of reticulin protein and form a network or mesh.

  3. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    An S-layer (surface layer) is a cell surface protein layer found in many different bacteria and in some archaea, where it serves as the cell wall. All S-layers are made up of a two-dimensional array of proteins and have a crystalline appearance, the symmetry of which differs between species.

  4. Reticular cell - Wikipedia

    en.wikipedia.org/wiki/Reticular_cell

    A reticular cell is a type of fibroblast that synthesizes collagen alpha-1(III) and uses it to produce extracellular reticular fibers.Reticular cells provide structural support, since they produce and maintain the thin networks of fibers that are a framework for most lymphoid organs.

    Plasmid – An extrachromosomal DNA molecule separate from the chromosomal DNA and capable of sexual replication, it is typically ring shaped and found in bacteria. Spindle fiber – The structure that separates the chromosomes into the daughter cells during cell division. Stroma – The colorless fluid surrounding the grana within the chloroplast.

  6. Reticular connective tissue - Wikipedia

    en.wikipedia.org/wiki/Reticular_connective_tissue

    Reticular connective tissue resembles areolar connective tissue, but the only fibers in its matrix are reticular fibers, which form a delicate network along which fibroblasts called reticular cells lie scattered. Although reticular fibers are widely distributed in the body, reticular tissue is limited to certain sites. It forms a labyrinth-like ...

  7. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    Prokaryotes (bacteria and archaea) usually undergo a vegetative cell division known as binary fission, where their genetic material is segregated equally into two daughter cells, but there are alternative manners of division, such as budding, that have been observed. All cell divisions, regardless of organism, are preceded by a single round of ...

  8. Loose connective tissue - Wikipedia

    en.wikipedia.org/wiki/Loose_connective_tissue

    Its fibers run in random directions and are mostly collagenous, but elastic and reticular fibers are also present. Areolar tissue is highly variable in appearance. In many serous membranes , it appears as a loose arrangement of collagenous and elastic fibers, scattered cells of various types; abundant ground substance ; numerous blood vessels.

  9. Bacteria - Wikipedia

    en.wikipedia.org/wiki/Bacteria

    In cell division, two identical clone daughter cells are produced. Some bacteria, while still reproducing asexually, form more complex reproductive structures that help disperse the newly formed daughter cells. Examples include fruiting body formation by myxobacteria and aerial hyphae formation by Streptomyces species, or budding. Budding ...
