Phloem Structure Phloem is composed of several cell types including sclerenchyma, parenchyma, sieve elements and companion cells. The sieve element and companion cell are found closely associated with each other in what is referred to as the sieve element/companion cell complex.
Xylem and phloem are the two types of vascular tissues found in plants. Xylem tissues transport water from the roots throughout the plant, while phloem transports food (suga â¦ rs) from photosysnthesis throughout the plant.Xylem: tubes that brings water and minerals from the roots into the leaf. There is a layer of living Phloem and there is a layer of living xylem. Both these layer produce dead tissue, the Phloem produces bark (dead protective outer layer), the â¦ xylem produces wood (dead supportive inner layer). Both the wood and the bark are dead.
