Plant+Transport

__**Assessment statements**__ 9.2.1 Outline how the root system provides a large surface area for mineral ion and water uptake by means of branching and root hairs. 9.2.2 List ways in which mineral ions in the soil move to the root. 9.2.3 Explain the process of mineral ion absorption from the soil into roots by active transport. 9.2.5 Define transpiration. 9.2.6 Explain how water is carried by the transpiration stream, including the structure of xylem vessels, transpiration pull, cohesion, adhesion and evaporation. 9.2.7 State that guard cells can regulate transpiration by opening and closing stomata. 9.2.8 State that the plant hormone abscisic acid causes the closing of stomata. 9.2.9 Explain how the abiotic factors light, temperature, wind and humidity, affect the rate of transpiration in a typical terrestrial plant. 9.2.10 Outline four adaptations of xerophytes that help to reduce transpiration. 9.2.11 Outline the role of phloem in active translocation of sugars (sucrose) and amino acids from source (photosynthetic tissue and storage organs) to sink (fruits, seeds, roots). 2.4.6 Explain the role of protein pumps and ATP in active transport across membranes.
