Epidermis covers the entire body of a herbaceous plant.
Guard cells are specialized epidermal cells found on root surfaces.
The epidermis is impervious to gas exchange.
Root hairs increase the surface area of epidermal cells on roots.
Cork cells replace epidermal cells on older woody plants.
Woody stems contain secondary growth.
Secondary phloem accumulates to form the wood.
The stem is organized into a central pith, wood, and outer bark.
Cork cambium produces waterproof cork cells that become bark.
The vascular cambium is located between the xylem and phloem of the vascular bundles in a woody stem.
Producing strong preservative chemicals.
Maintaining a waxy nonliving cuticle surface.
Building up and replacing an outer layer of dead cork (bark).
Having guard cells open to expose the soft juicy mesophyll of a leaf only when gas exchange is needed.
All of the above are correct.
