Form long tubes to carry water dissolve minerals from roots to leaves
Very thick walls containing lignin to support plant, causes xylem cells to die
End walls between cells broken to form a tube
No nucleus, cytoplasm, vacuole chloroplasts
Phloem
Carry dissolved sugars up and down plant
Consists of phloem vessel cells, no nucleus with limited cytoplasm. And the end walls of these have pores called sieve plates, these feature allow dissolved sugars to move through
Each vessel cell has a companion cell with lots of mitochondria for energy for Active Transport
