  2. Multicellular organism - Wikipedia

    en.wikipedia.org/wiki/Multicellular_organism

    One hypothesis for the origin of multicellularity is that a group of function-specific cells aggregated into a slug-like mass called a grex, which moved as a multicellular unit. This is essentially what slime molds do. Another hypothesis is that a primitive cell underwent nucleus division, thereby becoming a coenocyte.

    Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . 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.

  4. Cell biology - Wikipedia

    en.wikipedia.org/wiki/Cell_biology

    Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells. A cell is the basic unit of life that is responsible for the living and functioning of organisms. [3] Cell biology is the study of the structural and functional ...

  5. Cell (biology) - Wikipedia

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

    The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.

  6. Biological organisation - Wikipedia

    en.wikipedia.org/wiki/Biological_organisation

    The basic principle behind the organisation is the concept of emergence—the properties and functions found at a hierarchical level are not present and irrelevant at the lower levels. The biological organisation of life is a fundamental premise for numerous areas of scientific research , particularly in the medical sciences .

  7. List of human cell types - Wikipedia

    en.wikipedia.org/wiki/List_of_human_cell_types

    The Human Cell Atlas project, which started in 2016, had as one of its goals to "catalog all cell types (for example, immune cells or brain cells) and sub-types in the human body". [13] By 2018, the Human Cell Atlas description based the project on the assumption that "our characterization of the hundreds of types and subtypes of cells in the ...

  8. Cell–cell interaction - Wikipedia

    en.wikipedia.org/wiki/Cellcell_interaction

    Cellcell interaction refers to the direct interactions between cell surfaces that play a crucial role in the development and function of multicellular organisms. These interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is essential for the ...

  9. High- and low-level - Wikipedia

    en.wikipedia.org/wiki/High-_and_low-level

    In neuroscience, low-level would relate to the functioning of a cell (or part of a cell, or molecule) and high level to the overall function or activity of a neural system. [1] In documentation, a high-level document contains the executive summary, the low-level documents the technical specifications.
