Terrestrial plants take up huge amount water daily but most of it is lost to the air through transpiration. Ä Above all, water is a universal solvent. It is needed as a solvent, and all biochemical reactions of metabolic events take place in aqueous surroundings. The diffusion pressure of the individual substance is known as partial pressure. l It is a means of spreading of ions and other substances throughout the protoplast. l Density: The rate of diffusion of a substance (especially gas) is inversely proportional to the square root of its relative density, i.e., (Grahm’s law). l The physiological (bio-physicochemical) behaviour of water can be dealt with following heads: Ä In many higher plants, water acts as an agent of pollination and dispersal of seeds and fruits. However, transpirational loss of water is equally essential for providing cooling effects upon the plants concerned. Best Videos, Notes & Tests for your Most Important Exams. Ä It takes a direct part in many metabolic reactions. l The direction and rate of diffusion of a particular substance are independent of the presence of other substance in the medium.

Ä Water is the single largest chemical constituent (about 80-90%) of the protoplasm. Class 11 Transport in plants Plant Water Relation. Although water is an indispensable substance for plant growth, significantly less or high water quantity may have adverse effects on the same. l Diffusion may simply be defined as the free movement of molecules or ions from a region of higher concentration to lower concentration due to its kinetic energy until the molecules are evenly distributed throughout the available space. l It helps in the exchange of gases during photosynthesis and respiration. Crop Physiology, Department of Plant Sciences University of Saskatchewan, 51 Campus Drive, Saskatoon, S7N 5A8. l Temperature: The rate of diffusion increases with the temperature because temperature increases the kinetic energy of molecules. The evaporation of water from the surface of ocean, formation clouds and raining, is a natural cycle evolved during course of Evolution of this planet… Ä In lower plants, water is essential for fertilization. The distribution of water within a plant also varies, e.g., woody parts have relatively very little water, while soft parts mostly contain water.

PHYSIOLOGICAL BEHAVIOUR OF WATER Root pressure. It operates without the boundaries of the Second Law of Thermodynamics because it demonstrates nature’s tendency to wind down, as evidenced by increasing entropy. Home. Importance Transport in Plants Class 11 Notes: Water Potential. At this point, the pressure decreases to an extent where the protoplasm of the cell peels away from the cell … Ä Water present in vacuoles and cytoplasm helps in maintaining the rigidity (mechanical support) of the cells and hence the plant as a whole. A mature corn plant … For example, it is an important reactant (the source of electrons) during photosynthesis and an essential byproduct of respiration. Even dry seeds have a small amount of water (10-15%) without which they cannot remain alive. Diffusion The plant cells wilt in this condition. The hydration of protoplasm is highly essential for the proper functioning of the various cellular organelles.

As various ions from the soil are actively transported into the vascular tissues of the roots, water follows its potential gradient and increases the pressure inside the xylem and this positive pressure is called root pressure. It increases entropy and decreases Gibbs free energy, and, therefore, is thermodynamically favourable. Added to this water is also found in the atmosphere in the form of Hydrospheric mantle. Class 11 Biology Photosynthesis In Higher Plants Cyclic and non-cyclic photo-phosphorylation The process in which ATP is synthesised by cells in mitochondria and chloroplasts is named phosphorylation. l Diffusion pressure gradient: The rate of diffusion is directly proportional to the difference of diffusion pressure at the two ends of a system and inversely proportional to the distance between the two.
