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.
Phloem is a type of tissue found in plants. Along with xylem, phloem makes up the transport system within plants. Phloem and xylem are completely separate within the transport system. Both tissues are found throughout plants and each carries different substances to and from different parts of the plant.hloem, and xylem, tissue is arranged so that cells join end to end to form long tubes throughout the plant. The cells that make up the transport system have been modified to allow easier transport through the plant. In xylem tissue, the cells are dead.
