The importance of water in the physiology of plants makes it desirable to have an understanding of the nature and origin of the forces responsible for the movement of water into and out of plant cells and tissues. Only incidental attention will be given to the absorption and translocation of ...
The drivingforce for the uptake of water by the roots is the difference in theplant water and soil water potential existing between the soilsolution adjacent to the roots and the root xylem. In case oftranspiring plants, this driving force is mainly due to the tension(negative pressure) ...
Water is the most limiting abiotic (non-living) factor to plant growth and productivity, and a principal determinant of vegetation distributions worldwide. Since antiquity, humans have recognized plants' thirst for water as evidenced by the existence of irrigation systems at the beginning of ...
The objective of this study was to develop a sensitive means of control to optimize nutrient concentrations in the root zone of a soilless system, considering plant water and nutrient uptake, and solution circulation rates. A model is proposed to simulate ornamental plants' growth in a channel wi...
increase permeability of cells to water by in corporation of the molecules into the lipid layer of the cytoplasmic membrane, thereby changing the membrane from a phase characterized by a high activation energy for water transport to a phase where only the effect of the viscosity of water is ...
have less tissue water after exposure to cool autumn temperatures than plants from the Southern Great Plains. It is generally assumed that the reduced tissue water content of northern compared to southern cultivars is due to an impedance to water uptake by northern plants as a result of the low...
34.11: Water- en mineraalopname Gespecialiseerde weefsels in plantenwortels zijn geëvolueerd om water, mineralen en sommige ionen uit de bodem op te vangen. Wortels vertonen een verschillende vertakkingspatronen die dit proces vergemakkelijken. De buitenste wortelcellen hebben gespecialise...
2. Defining the Process: The process of water uptake by these molecules is a specific type of absorption. It does not involve the dissolution of the water into the molecules but rather the absorption of water. 3. Identifying the Term: The term used for this specific uptake of water by hem...
15 The graph shows the rate of uptake of magnesium ions by two similar plants, X and Y.The roots of each plant were placed in a range of solutions. Each solution contained a different concentration of magnesium ions. All other conditions were kept constant.plant X rate of uptake of ions ...
