The ground tissue comprises the bulk of the primary plant body. Parenchyma, collenchyma, and sclerenchyma cells are common in the ground tissue. Vascular tissue transports food, water, hormones and minerals within the plant. Vascular tissue includes xylem, phloem, parenchyma, and cambium cells. Two views of the structure of the root and root meristem.
There are two types of vascular tissue: xylem, which moves water, and phloem, which moves food. These structures are arranged differently in monocots and dicots. In monocots, which are flowering plants with only one seed leaf, the xylem and phloem are found in paired bundles throughout the stem.
