Xylem & Phloem (CIE IGCSE Biology: Co-ordinated Sciences (Double Award))

• Plants contain two types of transport vessel:
  • Xylem (pronounced: zi-lem) vessels – transport water and minerals from the roots to the stem and leaves. They also offer support to the plant within the stem
  • Phloem (pronounced: flow-em) vessels – transport food materials (mainly sucrose and amino acids) made by the plant from photosynthesising leaves to non-photosynthesising regions in the roots and stem 
• These vessels are arranged throughout the root, stem and leaves in groups called vascular bundles
