The sieve tube elements are separated by sieve plates 7 of 19 Xylem Vessels The tubes which carry water up the plant 8 of 19 Plasmodesmata Gaps in the cell wall containing cytoplasm that connects two cells 9 of 19 Potometer A device that can meausre the rate of water uptake as a leafy stem transpires 10 of 19 Transpiration The loss of water vapour from the aerial parts of a plant, mostly through the stomata in the leaves 11 of 19 Adhesion The attraction between water molecules and the walls of the xylem vessel 12 of 19 Cohesion The attraction between water molecules caused by hydrogen bonds 13 of 19 Hydrophyte A plant adapted to living in water or where the ground is very wet 14 of 19 Xerophyte A plant adapted to living in dry conditions 15 of 19 Assimilates Substances that have become a part of the plant 16 of 19 Sink A part of the plant where those materials are removed from the transport system 17 of 19 Source A part of the plant that loads materials into the transport system 18 of 19 Translocation The transport of assimilates throughout a plant 19 of 19
