b) Transpiration is very low and absorption is high. Some plant species do not generate root pressure. Please choose the correct answer … Capillary action and root pressure can support a column of water some two to three meters high, but taller trees--all trees, in fact, at maturity--obviously require more force. Clearly, there are several studies reporting a close correlation between root pressure exudation, expression of aquaporins, and hydraulic conductivity of the root (e.g. Until about age 64, high blood pressure is more common in men. In tall plants, root pressure is not enough, but it contributes partially to the ascent of sap. c) Transpiration is very high and absorption is also high. The risk of high blood pressure increases as you age. The root pressure is the pressure which is exerted on the liquid contents of the fully turgid cortex cells of the root, forcing some of it into the xylem vessels and up through the stem. Root pressure is basically the idea that a plant's roots can either maintain a higher or lower pressure based on its surroundings. Women are more likely to develop high blood pressure after age 65. Moreover, root pressure can be measured by the manometer. As per the natural phenomenon of osmosis, the water molecules naturally flows from the area of low mineral concentration to the area of high mineral concentration, and this flow of water into the root pressurizes it. In short plants, root pressure is largely involved in transporting water and minerals through the xylem to the top of the plant. Root pressure can move water a long distance up the xylem because of the higher water potential of the xylem in comparison to the water potential in the surrounding cells. It does this in order to promote or discourage nutrient uptake. False Root pressure can move water a short distance up the xylem because of the lower water potential of the xylem in comparison to the water potential in the surrounding cells. Children, pregnant and breastfeeding women, and those with kidney disease, heart disease, or high blood pressure should avoid licorice products. High blood pressure is particularly common among people of African heritage, often developing at an earlier age than it does in whites. The range of systolic blood pressure for most healthy adults falls between 90 and 120 millimeters of mercury (mm Hg). During root pressure, water passes through the root tissues freely, but the minerals do not (the root is a semi-permeable barrier). Normal diastolic blood pressure ranges between 60 and 80 mm Hg. a) Transpiration is high and absorption is very low. 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. It is a vital phenomenon and depends upon the activity of the living cells of the root. d) Transpiration and absorption are both low. Blood pressure always is higher when the heart is pumping (squeezing) than when it is relaxing. Race. 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.
