  2. Osmosis - Wikipedia

    en.wikipedia.org/wiki/Osmosis

    The process of osmosis over a semipermeable membrane.The blue dots represent particles driving the osmotic gradient. Osmosis (/ ɒ z ˈ m oʊ s ɪ s /, US also / ɒ s-/) [1] is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential (region of lower solute concentration) to a region of low water potential ...

  3. Osmoregulation - Wikipedia

    en.wikipedia.org/wiki/Osmoregulation

    Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.

    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.

  5. Homeostasis - Wikipedia

    en.wikipedia.org/wiki/Homeostasis

    The best-known homeostatic mechanisms in humans and other mammals are regulators that keep the composition of the extracellular fluid (or the "internal environment") constant, especially with regard to the temperature, pH, osmolality, and the concentrations of sodium, potassium, glucose, carbon dioxide, and oxygen.

  6. Osmotic shock - Wikipedia

    en.wikipedia.org/wiki/Osmotic_shock

    Current research also suggests that osmotic stress in cells and tissues may significantly contribute to many human diseases. [6] In eukaryotes, calcium acts as one of the primary regulators of osmotic stress. Intracellular calcium levels rise during hypo-osmotic and hyper-osmotic stresses.

    Histology – also known as microscopic anatomy or microanatomy, the branch of biology which studies the microscopic anatomy of biological tissues. Neuroanatomy – the study of the nervous system. Osteology – study of bones. Radiographic anatomy – study of anatomy through radiography; Surface anatomy – study of external features of a body

  8. Turgor pressure - Wikipedia

    en.wikipedia.org/wiki/Turgor_pressure

    Turgor pressure can be deduced when the total water potential, Ψ w, and the osmotic potential, Ψ s, are known in a water potential equation. [30] These equations are used to measure the total water potential of a plant by using variables such as matric potential, osmotic potential, pressure potential, gravitational effects and turgor pressure ...

    Moreover, they discovered the Cori cycle, also known as the Lactic acid cycle, [47] which describes how muscle tissue converts glycogen into lactic acid via lactic acid fermentation. Barbara McClintock was rewarded the 1983 Nobel Prize in Physiology or Medicine for the discovery of genetic transposition. McClintock is the only female recipient ...
