Guttation in plant leaves. (c) Process by which water enters root hairs. Guttation occurs only from plants growing in moist warm soil, when the air is humid, and transpiration is very low. Guttation is caused by positive hydrostatic pressure which develops in the xylem cells of the root. Guttation is not to be confused with dew, which condenses from the atmosphere onto the plant surface. The guttation usually occurs in the morning time when the atmosphere humidity will be high and the rate of transpiration will be low. Short answer type | Q 5.4 | Page 52.

As nouns the difference between guttation and bleeding is that guttation is (botany) the exudation of drops of water from the leaves of some vascular plants as a result of root pressure while bleeding is the flow or loss of blood from a damaged blood vessel. Tiny, specialized cells on the surface of a leaf or stem are connected to veins and sap channels of the plant. (b) Guttation is another name for bleeding in plants. This particular happens in plants growing in warm humid conditions. Guttation is more well-known in some vascular plants. VIEW SOLUTION. An example of guttation is visible in the figure below. State true or false with reason . Guttation also occurs in another situation: when the amount of water absorbed by the roots is greater than the plant's ability to remove water from the leaves.
