Transport and exchange surfaces in plants
Why this, why now
This unit covers water and mineral uptake in plants, focusing on root hair cells, xylem, and phloem. It includes transpiration, translocation, and factors affecting water uptake. Emphasis is on rate calculations, graph interpretation, experiments, and data analysis.
