Question
Classify the features as characteristic of the epidermis, periderm or secretory tissue. EPIDERMIS PERIDERM SECRETORY TISSUE Typically only 1 cell thick, though velamen roots can be much thicker. Derived from the parenchyma. Produce substances (e.g. nectar, latex, plant hormones) that will be transported outside the cell. Composed of several cell types, some of which are specialized (e.g. guard cells). Known as the outer bark, It is made up of dead, boxlike cork cells. Waterproof because its cells contain suberin in their walls. Protects the phloem and other tissues of woody planta from desiccation and damage. Secretes cutin to form its protective cuticle layer.Explanation / Answer
