Xylem = conducts water up a stem, THICK cell walls
Phloem = conducts photosynthetic products, thin cell walls

Week 4 Lab:
Xylem = conducts water up a stem, THICK cell walls
Tracheids – conduction AND mechanical support
Vessel Elements – conduction only. Often with fibers (support).

Week 4 Lab:
Phloem = conducts photosynthetic products, thin cell walls
Sieve Tube Members = conduct photosynthates. NO NUCLEUS!Companion Cells = “metabolic backpacks”
for STMs
