Guard cells, chloroplast-containing cells scattered throughout the epidermal layers regulate the opening and closing of the stoma. Periderm tissue forms the outer bark of woody plants and will be discussed later. Observe the prepared slide of a leaf epidermis and compare with the micrograph below.
The inner bark, in contrast, has living cells with nutrient laden cell sap, organelles, and stored starch. Most importantly, the phloem cells with their sugary contents are located here. The inner bark is the chief target for animals that feed on bark. Young twigs and branches are preferred because they have a higher proportion of inner to outer bark and lower concentrations of anti-digestion compounds such as lignin and phenols. There are considerable differences among species of trees, but all barks contain sugars, starch,
