VASCULAR BUNDLES rhe distinct group of cells is called as vascular bundles .there are two.types of vascular bundles called xylem and the phloem . Xylem is the thick cell walled tissue that transport water and minerals from the soil to the other parts of the plants .Phloem transports food to the leaves to the rest of the plant
