question: Above the meristem, the rest of the root is covered with a single layer of what type of cells, which may have root hairs?
distractor3: vegetative
distractor1: dermal
distractor2: single celled
correct_answer: epidermal
support: Above the meristem, the rest of the root is covered with a single layer of epidermal cells. These cells may have root hairs that increase the surface area for the absorption of water and minerals from the soil. Beneath the epidermis is ground tissue, which may be filled with stored starch. Bundles of vascular tissues form the center of the root. Waxy layers waterproof the vascular tissues so they don’t leak, making them more efficient at carrying fluids. Secondary meristem is located within and around the vascular tissues. This is where growth in thickness occurs.
