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.
The two types of vascular tissue are xylem (dead cells) and phloem (living cells). The xylem carries water and dissolved minerals upward from the roots through the stem and leaves of the plant. Phloem is responsible for distributing the products of photosynthesis, such as amino acids and carbohydrates, from the leaves to the rest of the plant.
