Xylem and phloem are made up of more than one type of cells. These cells function in coordination to perform various functions.

Xylem conducts water and minerals and provides support to the plant. It is made up of tracheids, xylem parenchyma, and xylem fibres. Phloem conducts food materials to various parts of the plant. It comprises of sieve tubes, phloem parenchyma, companion cells, and phloem fibres. That is why they are known as complex tissues.
