  2. Cell theory - Wikipedia

    en.wikipedia.org/wiki/Cell_theory

    The generally accepted parts of modern cell theory include: All known living things are made up of one or more cells [13] All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms. [14] The activity of an organism depends on the total activity of independent ...

  3. 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.

  4. Fences and pickets model of plasma membrane structure

    en.wikipedia.org/wiki/Fences_and_pickets_model...

    The actin-based membrane skeleton (MSK) meshwork is directly situated on the cytoplasmic surface of the plasma membrane. Membrane skeleton fence, or membrane skeleton corralling model, suggests that this meshwork is likely to partition the plasma membrane into many small compartments with regard to the lateral diffusion of membrane molecules.

  5. 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 ...

  6. Biological system - Wikipedia

    en.wikipedia.org/wiki/Biological_system

    The exact components of a cell are determined by whether the cell is a eukaryote or prokaryote. [7] Nucleus (eukaryotic only): storage of genetic material; control center of the cell. Cytosol: component of the cytoplasm consisting of jelly-like fluid in which organelles are suspended within; Cell membrane (plasma membrane):

  7. Anatomical model - Wikipedia

    en.wikipedia.org/wiki/Anatomical_model

    The model may show the anatomy partially dissected, or have removable parts allowing the student to remove and inspect the modelled body parts. Some models may have changeable genital inserts and other interchangeable parts which permit a unisex model to represent an individual of either sex. [citation needed]

  8. Outline of cell biology - Wikipedia

    en.wikipedia.org/wiki/Outline_of_cell_biology

    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.

  9. Rudolf Virchow - Wikipedia

    en.wikipedia.org/wiki/Rudolf_Virchow

    Virchow's cellular theory was encapsulated in the epigram Omnis cellula e cellula ("all cells (come) from cells"), which he published in 1855. [ 9 ] [ 22 ] [ 32 ] (The epigram was actually coined by François-Vincent Raspail , but popularized by Virchow.) [ 33 ] It is a rejection of the concept of spontaneous generation, which held that ...
