  3. Disk sector - Wikipedia

    en.wikipedia.org/wiki/Disk_sector

    In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories.To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.

  4. Subcellular localization - Wikipedia

    en.wikipedia.org/wiki/Subcellular_localization

    The cytoplasm, the cytoplasmic membrane and the cell wall are subcellular localizations, whereas the extracellular environment is clearly not. Most Gram-negative bacteria also contain an outer membrane and periplasmic space. Unlike eukaryotes, most bacteria contain no membrane-bound organelles, however there are some exceptions (i.e. magnetosomes).

    The secondary cell wall, a thick layer formed inside the primary cell wall after the cell is fully grown. It is not found in all cell types. It is not found in all cell types. Some cells, such as the conducting cells in xylem , possess a secondary wall containing lignin , which strengthens and waterproofs the wall.

Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.

  8. Colony (biology) - Wikipedia

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

    A microbial colony is defined as a visible cluster of microorganisms growing on the surface of or within a solid medium, presumably cultured from a single cell. [11] Because the colony is clonal , with all organisms in it descending from a single ancestor (assuming no contamination ), they are genetically identical, except for any mutations ...

  9. Wall-associated kinase - Wikipedia

    en.wikipedia.org/wiki/Wall-Associated_Kinase

    Wall-associated kinases (WAKs) are one of many classes of plant proteins known to serve as a medium between the extracellular matrix (ECM) and cytoplasm of cell walls.They are serine-threonine kinases that contain epidermal growth factor (EGF) repeats, a cytoplasmic kinase and are located in the cell walls.
