Plant Morphology Meristem Tissue- embryonic tissue located at the tips of roots and stem apices (herbaceous & woody plants) and cambium layers (woody plants). Parenchyma - unspecialized cells occurring throughout the plant. Sclerenchyma- hollow, non-living cells with thick walls; structural support

Transport System Xylem Tissue- transports water and minerals from the roots to the leaves; Phloem Tissue- transports organic nutrients from the leaves to the roots

Herbaceous and Woody Stems Herbaceous plants exhibit only primary growth while woody plants have secondary growth.
