Vascular Tissues and Cell Inclusions
Vascular Tissues and Cell Inclusions
This chapter examines the vascular tissues and cell inclusions in palms. It identifies the two basic types of vascular tissues involved with long distance transport: xylem that carries mainly water, and phloem that carries mainly sugars and other organic compounds. The two tissues occur together in vascular bundles, which may contain only phloem when small. The chapter discusses xylem and tracheary elements (tracheary element distribution and vessel elements), phloem and sieve elements (histology and cellular details), and cell inclusions (silica, raphide sacs and mucilage canals, tannins, starch). These cell types not themselves organized into discrete tissues, but distributed within other, mainly ground, tissues. They may still have a specific location, as with silica cells which are always associated with fibres.
