Vascular System (veins): Xylem and Phloem

• There are two tubes found inside most plants: xylem and phloem.

Xylem : transports nutrients and water from the roots of the plant to every area of the plant.

Phloem : transports nutrients (mostly sugars that are made during photosynthesis from the leaves to the rest of the plant
