Transpiration • The flow of water up through a plant • Water is absorbed into the plant’s roots via osmosis • The capillary cohesive forces allow for the water to reach the leaves • At the leaves, the water evaporates into the atmosphere as water vapour
Light intensity Humidity Air Movement Water Availability Temperature Factors Affecting Transpiration
Mineral Transport in Plants Minerals are absorbed from the soil through the root hairs and travel to the xylem.
Translocation • The movement of sugars in solution from the leaves, through the sieve tubes to other parts of the plant • Sugars travel through phloem • Driven by active pumping of sugars, therefore requiring the expenditure of energy by the plant
