Water helps in the transpiration, which is very essential for maintaining the absorption of nutrient from the soil. For example, water is necessary for a plant to maintain turgor, which gives a plant rigidity and shape. Photosynthesis is an important biochemical pathway involving the production of sugar (glucose) from light, water and carbon dioxide and releasing oxygen. Plant growth depends on rapid rates of ex-change. Plants receive most of their water through the root system. 0000001927 00000 n Water is a vital component to the survival of every plant in the world as it is aids in the way that they obtain their food (through the process of photosynthesis), grow (cell division, mitosis), respire (cellular respiration) and how they keep their formation (rigidity). 66 0 obj <>stream Role of water in cooling the plant body: Normally, every plant through out the day will be well exposed to high intensity of Sunlight. 28 0 obj <> endobj 9.
