• Dermal tissue - forms the boundary between the plant and the external world
  • epedermis - single layered group of cells covering a plant, especially the leaf and young tissues of a vascular plant, including stems and roots. It protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorps water and mineral nutrients.
  • cork - external, secondary tissue impermeable to water and gases.
  • periderm - secondary covering
• Vascular tissue - conducts fluids and nutrients internally
  • xylem - primary water-conducting tissue
  • phloem - the living tissue that carries sugar and organic nutrients throughout the plant
• Ground tissue - manufactures nutrients by photosynthesis and stores reserve nutrients
  • parenchyma - forms the cortex and pith of stems, the cortex of roots, the mesophyll, the pulp of fruits, the endosperm of seeds, and the photosynthetic areas of a leaf
  • collenchyma
  • sclerenchyma
• Meristematic tissue - a tissue in plants consisting of undifferentiated cells and found in zones of the plant where growth can take place — the roots and shoots
