  2. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Hypoxia can affect the nutrient uptake of a plant because, without oxygen present, respiration becomes inhibited within the root cells. The nutrient film technique is a hydroponic technique in which the roots are not fully submerged. Incomplete submergence allows for adequate aeration of the roots, while a "film" thin layer of nutrient-rich ...

  3. Biological roles of the elements - Wikipedia

    en.wikipedia.org/wiki/Biological_roles_of_the...

    In plants, it has important roles in nucleic acid metabolism, carbohydrate and protein metabolism, cell wall synthesis, cell wall structure, membrane integrity and function, and phenol metabolism. [20] Probably essential to animals, for reasons not well understood. [21] Toxic to both animals and plants. [22] bromine: 35: 5

  4. Nutrient - Wikipedia

    en.wikipedia.org/wiki/Nutrient

    A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons.

  5. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  6. Nutrition - Wikipedia

    en.wikipedia.org/wiki/Nutrition

    Schematic of photosynthesis in plants. The carbohydrates produced are stored in or used by the plant. Most plants obtain nutrients through inorganic substances absorbed from the soil or the atmosphere. Carbon, hydrogen, oxygen, nitrogen, and sulfur are essential nutrients that make up organic material in a plant and allow enzymic processes.

  7. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    Plant cells also contain chlorophyll, a chemical compound that interacts with light in a way that enables plants to manufacture their own nutrients rather than consuming other living things as animals do. Thirdly, plant physiology deals with interactions between cells, tissues, and organs within a plant. Different cells and tissues are ...

    Protein is a nutrient that's essential for muscle growth and maintenance, metabolism regulation, and a healthy immune system. "Protein from steak is particularly favorable," says Bikman, because ...

  9. Nutrient sensing - Wikipedia

    en.wikipedia.org/wiki/Nutrient_sensing

    Higher plants require a number of essential nutrient elements for completing their life cycles. Mineral nutrients are mainly acquired by roots from the rhizosphere and are subsequently distributed to shoots. To overcome with nutrient limitations, plants have evolved a set of elaborate responses consisting of sensing mechanisms and signaling ...
