Phloem and xylem cells

• Phloem and xylem cells are specialised from transporting substances.
• Phloem and xylem cells for phloem and xylem tubes, which transport substances such as food and water around plants.
• To form the tubes, the cells are long and joined end to end.
• Xylem cells are hollow in the centre and phloem cells have very few sub cellular structures so that stuff can flow through them.
