Cohesion holds hydrogen bonds together to create tension on water. Because water is attracted to other molecules, adhesive forces pull the liquid to other molecules. Evaporation is the process of liquid changing to a gas as a result of heat. Xylem is a transport tissue which transports water and solutes from the roots to the leaves.Leaves are adapted for photosynthesis by having a large surface area, and contain stomata, (which are openings) to allow carbon dioxide into the leaf. Plants transpire in order to cool the leaf, vaporisation means that the plants lose water to cool themselves down. If it doesn’t then consequently the plant will dry due to high temperatures . Light, temperature, wind and humidity all affect transpiration rate. Wilting is the condition that arises in plants when more water is lost by evaporation than is absorbed from the soil, this results in the plant drooping and possible death. Xerophytes live in deserts where water is scarce and evaporation is rapid, or in windy habitats where evaporation can also be rapid.
