  2. Cytolysis - Wikipedia

    en.wikipedia.org/wiki/Cytolysis

    Cytolysis. A red blood cell in a hypotonic solution, causing water to move into the cell. Blood cells in solutions with different osmotic pressure. Cytolysis would result in the image on the far right. Cytolysis, or osmotic lysis, occurs when the liquid outside a cell enters the cell causing it to burst. Water can enter the cell by diffusion ...

  3. Cytoplasmic streaming - Wikipedia

    en.wikipedia.org/wiki/Cytoplasmic_streaming

    Cytoplasmic streaming, also called protoplasmic streaming and cyclosis, is the flow of the cytoplasm inside the cell, driven by forces from the cytoskeleton. [1] It is likely that its function is, at least in part, to speed up the transport of molecules and organelles around the cell. It is usually observed in large plant and animal cells ...

  4. Cytolysin - Wikipedia

    en.wikipedia.org/wiki/Cytolysin

    Cytolysin. Cytolysin refers to the substance secreted by microorganisms, plants or animals that is specifically toxic to individual cells, [1][2] in many cases causing their dissolution through lysis. Cytolysins that have a specific action for certain cells are named accordingly. For instance, the cytolysins responsible for the destruction of ...

  5. Plasmolysis - Wikipedia

    en.wikipedia.org/wiki/Plasmolysis

    Plasmolysis is the process in which cells lose water in a hypertonic solution. The reverse process, deplasmolysis or cytolysis, can occur if the cell is in a hypotonic solution resulting in a lower external osmotic pressure and a net flow of water into the cell. Through observation of plasmolysis and deplasmolysis, it is possible to determine ...

  6. Lysis - Wikipedia

    en.wikipedia.org/wiki/Lysis

    Lysis (/ ˈlaɪsɪs / LY-sis) is the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, "lytic" / ˈlɪtɪk / LIT-ik) mechanisms that compromise its integrity. A fluid containing the contents of lysed cells is called a lysate. In molecular biology, biochemistry, and cell biology laboratories, cell cultures ...

  7. 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.

  8. Mathematical and theoretical biology - Wikipedia

    en.wikipedia.org/wiki/Mathematical_and...

    Mathematical and theoretical biology, or biomathematics, is a branch of biology which employs theoretical analysis, mathematical models and abstractions of living organisms to investigate the principles that govern the structure, development and behavior of the systems, as opposed to experimental biology which deals with the conduction of ...

  9. Cytoplasm - Wikipedia

    en.wikipedia.org/wiki/Cytoplasm

    Cytoplasm. In cell biology, the cytoplasm describes all material within a eukaryotic cell, enclosed by the cell membrane, except for the cell nucleus. The material inside the nucleus and contained within the nuclear membrane is termed the nucleoplasm. The main components of the cytoplasm are the cytosol (a gel-like substance), the organelles ...
