Question

Which pressure is responsible for Guttation?

Answer 1

As we knew that, plants are independent as they prepare their own food and other activities like-transpiration, guttation, photosynthesis are all correlated to each other which help plants to grow. Guttation is the process where water or tiny droplets of water are being released at the upper surface of plants’ leaf to maintain the osmoregulation level inside.

Complete answer:
Guttation is the phenomenon of secreting water from the pores of plants. It is the exudation of water from xylem sap. Examples of plants carrying guttation are- grasses.
Leaves are the part of the plant which absorbs water and other nutrients as it is an aerial part of the plant. Leaves also absorb sunlight for the photosynthesis to occur. Usually, you must have seen in the early morning when we walk on grass, grass feels wet because of guttation. Guttation occurred at night time as the transpiration rate sometimes can be low or less in some plants.
The pressure which is responsible for guttation to happen is Root pressure. Root pressure mainly functions as forcing water to travel to the upper parts of plants. Roots take up nutrients and send to the aerial parts of plants in return leaves conduct the photosynthesis process which provides food to the entire plant. leaves release water from its surface when excessive water enters the cell sap. The veins and veinlets system in leaves helps in carrying nutrients to different parts of the plant.

Note:
Leaves check transpiration because it reaches water to every part or not. Transpiration decreases the pressure called hydrostatic pressure in plants due to which water easily moves upward due to this capillary action. leaves apart from assembling nutrients and transportation, it absorbs water also but the shiny and glabrous part are different.
