A. VASCULAR BUNDLES
These contain two types of vessel that transport substances around the plant:
• Xylem - transports water and mineral ions from roots to leaves (up).
• Phloem - transports sugar, as sucrose, in both directions (up and down).
In the ROOT
Xylem
Phloem
• Easy to remember as xylem tissue is shaped like the letter ‘X’, for Xylem.
In the STEM Vascular
bundle
Xylem
Phloem
• Xylem tissue is on the inside of the vascular bundle and phloem tissue is on the outside.
