  2. Mineral absorption - Wikipedia

    en.wikipedia.org/wiki/Mineral_absorption

    In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are ...

  3. Nutrient cycle - Wikipedia

    en.wikipedia.org/wiki/Nutrient_cycle

    Energy flow is a unidirectional and noncyclic pathway, whereas the movement of mineral nutrients is cyclic. Mineral cycles include the carbon cycle, sulfur cycle, nitrogen cycle, water cycle, phosphorus cycle, oxygen cycle, among others that continually recycle along with other mineral nutrients into productive ecological nutrition.

  4. Phosphorescence - Wikipedia

    en.wikipedia.org/wiki/Phosphorescence

    [24] [25] In turn, to inhibit competitive non-radiative deactivation pathways, including vibrational relaxation and oxygen quenching and triplet-triplet annihilations, organic phosphors have to be embedded in rigid matrices such as polymers, and molecular solids (crystals, [26] covalent organic frameworks, [27] and others).

  5. Computer graphics lighting - Wikipedia

    en.wikipedia.org/wiki/Computer_graphics_lighting

    Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity. Graphics artists can choose from a variety of light sources ...

  6. Copper in biology - Wikipedia

    en.wikipedia.org/wiki/Copper_in_biology

    Copper supplements are not prescription medicines, and are available at vitamin and herb stores and grocery stores and online retailers. Different forms of copper supplementation have different absorption rates. For example, the absorption of copper from cupric oxide supplements is lower than that from copper gluconate, copper sulfate, or ...

  7. Isotopic labeling - Wikipedia

    en.wikipedia.org/wiki/Isotopic_labeling

    Aspects of mineral nutrition/metabolism that are studied include absorption (from the gastrointestinal tract into the body), distribution, storage, excretion and the kinetics of these processes. Isotope tracers are administered to subjects orally (with or without food, or with a mineral supplement) and/or intravenously.

  8. Absorption of water - Wikipedia

    en.wikipedia.org/wiki/Absorption_of_water

    This gradient of water potential causes endosmosis. The endosmosis of water continues until the water potential both in the root and soil becomes equal. It is the absorption of minerals that utilise metabolic energy, but not water absorption. Hence, the absorption of water is indirectly an active process in a plant's life.

  9. Magnesium in biology - Wikipedia

    en.wikipedia.org/wiki/Magnesium_in_biology

    Magnesium and vitamin D have a synergistic relationship in the body, meaning they work together to optimize each other's functions: [22] [23] Magnesium activates vitamin D; Vitamin D influences magnesium absorption. Bone health: They play crucial roles in calcium absorption and bone metabolism.
