Xylem = conducts water up a stem, THICK cell walls

Tracheids – conduction AND mechanical support

Vessel Elements – conduction only. Often with fibers (support).

Phloem = conducts photosynthetic products, thin cell walls

Sieve Tube Members = conduct photosynthates. NO NUCLEUS!Companion Cells = “metabolic backpacks”
