The pressure (the result of osmosis) exerted by the roots of vascular plants that moves water into the leaves and causes guttation.. Root pressure Meaning. Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or when transpiration is low during the day. osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves. root pressure synonyms, root pressure pronunciation, root pressure translation, English dictionary definition of root pressure. Root pressure is the lesser force and is important mainly in small plants at times when transpiration is not substantial, e.g., at nights. Root preesure is the pressure developed in the roots due to continued inward movement of water through cell-to-cell osmosis which helps in the ascent of cell sap upward through the stem. Root pressure – definition and experiment to demonstrate it. Biology. 0 0. All Free. Pronunciation: — Bot. How to pronounce, definition … Root pressure, in plants, the force that helps to drive fluids upward into the water-conducting vessels (xylem). Dictionary > Index R; Cite. 1 decade ago. Anonymous. for distance learning. When transpiration is high, xylem sap is usually under tension, rather than under pressure, due to transpirational pull.At night in some plants, root pressure causes guttation or exudation of drops of xylem sap from the tips or edges of leaves. 1870–75; Forum discussions with the word(s) "root pressure" in the title: No titles with the word(s) "root pressure". Study online pressure potential explanation with biology terms to prepare course for online degree programs. It is caused by active transport of mineral nutrient ions into the root xylem. transpiration is the loss of water from the aerial parts of the plants body. ... the rhizosphere represents a highly significant interface between biology and geology, an interfacial environment with broad consequences for earth's biogeochemistry and soil formation. Glossary of biology terms . Pressure potential definition and explanation in biology. Find definitions for: root' pres"sure. The key difference between root pressure and transpiration pull is that root pressure is the osmotic pressure developing in the root cells due to movement of water from soil solution to root cells while transpiration pull is the negative pressure developing at the top of the plant due to the evaporation of water from the surfaces of mesophyll cells. Stomatal mechanism – starch ↔ sugar interconversion and K+-ion mechanism. root pressure: Meaning and Definition of. ... Plant Biology osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.
