  2. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    Cell structure of a gram positive bacterium. In comparison to eukaryotes, the intracellular features of the bacterial cell are extremely simple. Bacteria do not contain organelles in the same sense as eukaryotes. Instead, the chromosome and perhaps ribosomes are the only easily observable intracellular structures found in all bacteria. There do ...

  3. Bacterial cellular morphologies - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cellular...

    Spiral bacteria are another major bacterial cell morphology. [2] [30] [31] [32] Spiral bacteria can be sub-classified as spirilla, spirochetes, or vibrios based on the number of twists per cell, cell thickness, cell flexibility, and motility. [33] Bacteria are known to evolve specific traits to survive in their ideal environment. [34]

  4. Bacteria - Wikipedia

    en.wikipedia.org/wiki/Bacteria

    Bacteria can be classified on the basis of cell structure, cellular metabolism or on differences in cell components, such as DNA, fatty acids, pigments, antigens and quinones. [117] While these schemes allowed the identification and classification of bacterial strains, it was unclear whether these differences represented variation between ...

    Note also that the cell wall is not a rigid structure in either plants or bacteria. If cell walls were truly rigid, plants could not wilt (think about it). The cell wall is a woven flexible framework that is made rigid primarily by the osmotic pressure exerted from the inside by the cell inside its membrane.

  6. Bacterial capsule - Wikipedia

    en.wikipedia.org/wiki/Bacterial_capsule

    The bacterial capsule is a large structure common to many bacteria. [1] It is a polysaccharide layer that lies outside the cell envelope, and is thus deemed part of the outer envelope of a bacterial cell. It is a well-organized layer, not easily washed off, and it can be the cause of various diseases.

  7. S-layer - Wikipedia

    en.wikipedia.org/wiki/S-layer

    An S-layer (surface layer) is a part of the cell envelope found in almost all archaea, as well as in many types of bacteria. [1] [2] The S-layers of both archaea and bacteria consists of a monomolecular layer composed of only one (or, in a few cases, two) identical proteins or glycoproteins. [3]

  8. Cell wall - Wikipedia

    en.wikipedia.org/wiki/Cell_wall

    Around the outside of the cell membrane is the bacterial cell wall. Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. [36] Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose ...

  9. Flagellum - Wikipedia

    en.wikipedia.org/wiki/Flagellum

    In the cell apex is the basal body that is the anchoring site for a flagellum. Basal bodies originate from and have a substructure similar to that of centrioles, with nine peripheral microtubule triplets (see structure at bottom center of image). The "9+2" structure is visible in this cross-section micrograph of an axoneme.
