- Comment
- The epidermis can be composed of one or more layers of cells. In some species of vascular plants, the epidermis, which is a primary tissue, is replaced by periderm, which is secondary tissue, later in development. The epidermis can also include trichomes, stomatal pores, root hairs, and rhizoids.
