8.3) Transpiration Transpiration: is the loss of water vapour from plant leaves by evaporation of water at the surfaces of the mesophyll cells followed by the diffusion of water vapour through the stomata. The main force that draws water from the soil...
8.4) Translocation Translocation: is the movement of sucrose and amino acids in the phloem, from regions of production (the ‘source’) to regions of storage or to regions where they are used in respiration or growth (the ‘sink’). This is the movement of...
8.1) Transport in plants Xylem vessels: transport water and dissolved minerals from the root up to all the other parts of the plant. Phloem Vessels: The function of Phloem Vessels is to transport food nutrients such as glucose from the leave to other parts of...
8.2) Water uptake Root hair cells: The root hairs are where most water absorption happens. They are long and thin so they can penetrate between soil particles, and they have a large surface area for absorption of water. Water passes from the soil water to the...
