CAIE IGCSE Biology 8.1.1 Functions of xylem & phloem: (a)
Practise matching xylem and phloem to their functions, using plant diagrams, stained stems and transport contexts in roots, stems and leaves.
How this is tested
- state that xylem transports water and mineral ions and helps support stems and leaves
- link phloem to translocation of sucrose and amino acids from sources to sinks
- choose the correct transport tissue from stained stems, root sections or vascular bundle diagrams
