<Li> Sclerenchyma (bast fibre) </Li> <P> In vascular plants, phloem (pronunciation: / ˈfləʊ. əm /) is the living tissue that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed . This transport process is called translocation . In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word φλοιός (phloios) meaning "bark". The term was introduced by Nägeli in 1858 . </P> <P> Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids . </P> <Ol> <Li> Xylem </Li> <Li> Phloem </Li> <Li> Cambium </Li> <Li> Pith </Li> <Li> Companion Cells </Li> </Ol>
