Stem - The stem is the main structure that supports leaves and flowers. As the stem increases in diameter due to production of secondary xylem and secondary phloem, the cortex and epidermis are eventually destroyed. The specialized plant cells include parenchyma cells, sclerenchyma cells, collenchyma cells, xylem cells and phloem cells. Parenchyma cells are the most common plant cells (Figure 2). Most ferns have rhizomes with no vertical stem. Nonvascular plants are considered to be the earliest living plants in the planet. The ground tissue usually consists mainly of parenchyma cells and fills in around the vascular tissue.
