Consequences of Guttation Guttation is basically harmless, provided that the water drips from the leaf. False. 2 Water lost in guttation is rich in minerals. b. when the root pressure is low and the rate of transpiration is high c. when the root pressure equals the rate of transpiration d. when the root pressure, as well as rate of transpiration, are high. Simply put, dew is formed on the plant’s surface from the condensation of moisture in the air. (True) 2. Transpiration is a physiological process. The watery drops consist of water in which many inorganic and organic substances are dissolved. Hydathodes are the minor openings at the leaf tip which is uncovered by the cuticle (Fig. Therefore, the water potential inside the plant is very high. On the other hand, the guttation which takes place in submerged aquatic plants being invisible may be designated as “aquatic guttation” (Pedersen, 1998). Caused by high water potential. The process of guttation takes place a. when the root pressure is high and the rate of transpiration is low. If false rewrite the wrong statement in its correct form: Transpiration is a physiological process . Soln. The process of guttation takes place a. when the root pressure is high and the rate of transpiration is low. True & False. Extra amount of transpiration can lead to the cause of wilting. Caused by root pressure. But it does not happen in the method of gutattion. It mostly takes place at night or early in the morning, when there is no transpiration and root pressure is high. But Guttation takes place at the time of night when the temperature is low and cold. Water is lost in the form of vapors. Join the 2 Crores+ Student community now! Guttation usually occurs when the plant it put 2:25 4.0k LIKES. • Transpiration is a controlled process, whereas guttation is not. In fact, about 97 – 99.5% of water intake is lost through the processes of transpiration and guttation. How to apply water? b. when the root pressure is low and the rate of transpiration is high c. when the root pressure equals the rate of transpiration d. when the root pressure as well as rate of transpiration are high.

Caused by root pressure. 5.The process of guttation takes place (a) when the root pressure is high and the rate of transpiration is low (b) when the root pressure is low and the rate of transpiration is high (c) when the root pressure equals the rate of transpiration (d) when the root pressure as well as rate of transpiration are high. Transpiration does not occur during the night because stomata are closed. Guttation is mostly exhibited by herbaceous plants e.g., Balsam, colossi etc. It is not uncommon to see, the loss of water through the bark. There is a difference between the two. Maths. … Other sources say it occurs when the stoma are closed at night while the roots continue to take in water, that when the stoma are closed, transpiration can't occur so guttation takes place. Biology. 2. 4), this allows guttation of surplus water through the leaves of herbaceous crop plants, such as mustard, grasses, and Saxifragaceae (saxifrage family; Huang, 1986). The process of guttation takes place a. when the root pressure is high and the rate of transpiration is low. Transpiration is the process of water movement through the plant and its subsequent evaporation through the leaves, stems and flowers. This is called as Guttation and takes place usually early in the morning when the rate of water absorption and the root pressure are higher while the transpiration is very low.

Guttation: Transpiration: Occurs early morning and at night. True. Fortunately the total amount of water lost by this method is again not that significant. This is called as guttation and takes place usually early in the morning when the rate of absorption and root pressure are high while the transpiration is very low. Guttation takes place due to the development of root pressure * Hydathodes are special type of stomata called water stomata through which guttation takes place. It occurs during the cold hours of night and early morning. Guttation takes place generally at _____. This happens in spite of suberization of bark cells. NCERT RD Sharma Cengage KC Sinha.
