Xylem and phloem plant tissue. Coloured scanning electron micrograph (SEM) of a transverse section through the stem of a woody plant. The vascular tissue seen here includes xylem (orange,centre),which transports water and mineral nutrients from the roots throughout the plant. Surrounding the xylem is the phloem (green),which transports carbohydrates and plant hormones around the plant. The phloem includes sieve plates.
