6. It occurs due to the development of root pressure. The root pressure increases which makes the water drops leave the plant through special type of pores on leaves known as Hydathodes. Root pressure is studied by removing the shoot of a plant near the soil level. In case there is excess water, the root pressure forces the water out of the tips of the leaves or the blades of the plants. (ii) Occurs through stomata, cuticle and lenticels. However, as mentioned earlier there is a difference between guttation and transpiration. There is a difference between the two. Transpiration is controlled by the activity of the guard cell. See more. Root pressure develops due to active absorption which depends on the active accumulation of solute in xylem sap. But only 1% of this amount is utilized by plants while 99 % is lost from the aerial parts of the plant. 8.6.8 Difference between Transpiration and Guttation Transpiration Guttation (i) Water is lost in the form of water vapor. What factors cause guttation? Guttation usually occurs as a consequence of a combination of high root pressure (which may be caused by different factors) and a low evaporation rate/too high humidity. When the stem is cut, the solution oozes from the cut end. Stomata is usually opened at day time and close at night. It is an uncontrolled phenomenon 6. The water comes out in the form of drops through pores in tips of leaves. 5. A process in which the moisture and other gaseous wastes are excreted through the stomata of the leaf, lenticels of the stem and fruits are termed as Transpiration. Guttation is a phenomenon which is caused by the root PRESSURE. As nouns the difference between guttation and exudation is that guttation is (botany) the exudation of drops of water from the leaves of some vascular plants as a result of root pressure … At the time when the water is lost down from the aerial portions of the plants in the form of vapors this method is known as Transpiration. Guttation water has many dissolved substances 5. Transpiration loses water in the form of vapors while Guttation loses in liquid form. The process of guttation has no cooling effect on the plants as it largely depends on root pressure. Exudation of liquid from roots and root hairs of woody plants also has been reported (Head, 1964), and, as this probably is caused by root pressure, it may be termed root guttation. In case there is excess water, the root pressure forces the water out of the tips of the leaves or the blades of the plants. Chemical content. Water loss in the form of water drops 2. Guttation definition, a process in which water in liquid form is given off by plants. Guttation: Loss of water in the form of liquid from the uninjured margins of the leaves is called guttation. (3) 1) Environmental conditions that restrict transpiration. Guttation may also occur during daytime if the plants are growing in moist or humid condition which increases root pressure. 6. Occurs through hydathodes * 3. 7. 1. 'Root Pressure'. Transpiration (i) It occurs through stomata, cuticle and lenticels. Guttation must not be confused with transpiration. Root pressure can be observed experimentally by cutting the stem of a well-watered plant on a humid day. Root pressure provides a force, which pushes water up the stem, but it is not enough to account for the movement of water to leaves at the top of the tallest trees. The transpiration rate must be slow in order for the root pressure to be higher than the transpirational pull. As nouns the difference between plant and guttation is that plant is an organism that is not an animal, especially an organism capable of photosynthesis typically a small or herbaceous organism of this kind, rather than a tree while guttation is (botany) the exudation of drops of water from the leaves of some vascular plants as a result of root pressure. Plant absorbs a large amount of water irrespective of their daily requirements. Guttation is not controlled by the opening and closing of guard cell. Root pressure: Root pressure is the hydrostatic 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 upwards through the stem. Answer: Difference between root pressure and transpiration pull in tabular form 3 points. Explanation: Transpiration. Guttation may also occur during daytime if the plants are growing in moist or humid condition which increases root pressure. (iii) Occurs during day time and at high temperature. 1. The process of guttation formation in fungi is unknown. During the process when water undergoes guttation it will also pick up minerals and enzymes, such a process is called a xylem sap.
