The phloem is comprised of the following major components: (1) sieve elements, (2) companion cells, (3) phloem sclerenchyma, and (4) phloem parenchyma. Phloem is composed of four kinds of cells: sieve elements, companion cells,phloem parenchyma and phloem fibres. Functions of vascular tissue: o Conduction of water (xylem) o Conduction of food (phloem) o Provide mechanical support (6). Companion cells are absent in pteridophytes and gymnosperms.
