Xylem (transport water in plants) 
* Thick secondary cell walls, often deposited unevenly in a coil-like pattern so that they may stretch 
* Dead at functional maturity. 
* Involved in the conduction of water and ions in the plant 
* Two types - tracheids and vessels 

Phloem (transport food in form of sugars +) 
* Involved in the transport of sucrose, other organic compounds, and some ions 
* Living at functional maturity 
o Protoplast may lack organelles and nucleus, though 
* End walls connect to each other via sieve-plates 
* Two types of cells in the phloem - sieve-tube members and companion cells
