Stems of most species
support leaves and
reproductive structures.
• Stems provide internal
transport.
• They produce new living
tissue, as root. They
continue to grow
throughout a plant’s life.

• Dicots and monocots differ in the internal
structure of stem regarding the arrangement
of the vascular structures (xylem and
phloem).
