This exam tips covers Common Misconceptions and Exam Tips within Plant Transport Systems for GCSE Biology. Xylem and phloem structure, water and sugar transport, root hair adaptations, translocation, and practical investigations It is section 16 of 18 in this topic. Treat this as a marking guide for what examiners are looking for, not just a fact list.
