The ground tissue comprises the bulk of the primary plant body. Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue.

Two views of the structure of the root and root meristem.
The vascular tissue system is important in transport. The vascular tissue system is composed of the xylem (transport of water and dissolved minerals) and phloem (transport of food-usually sucrose and other sugars-, nitrogen containing compounds, and hormones).The xylem and phloem in the primary plant body are usually closely associated in the form of vascular bundles.he vascular tissue system is important in transport.
