the phloem transports glucose and amino acids made from the plant from photosynthesising leaves to the rest of the plant
the vascular bundles includes the plant's phloem and xylem
xylem is responsible for water transportation, it has long narrow cells with thick walls that are lignified (made out of cellulose)
phloem is responsible for sugar transportation, it has sieve tube elements which have no nucleus or organelles so they can be easily filled with sugars
