POINTS TO REMEMBER Translocation: Transport of substances in plants over longer distances through the vascular tissue (Xylem and Phloem) is called translocation.
Means of transport: The transport of material into and out of the cells is carried out by a number of methods. These are diffusion, facilitated diffusion and active transport.
Diffusion : Diffusion occurs from region of higher concentration to region of lower concentration across the permeable membrane. It is passive and slow process. No energy expenditure takes place
Diffusion Particle net movement from; a region of HIGH concentration to a region of LOW concentration Movement of Particles to LowConcentration High Concentration Diffused Throughout Equilibrium
