Solution
The correct option is D All of the above
Epidermal cells make the outermost covering of primary plant body. They are compactly arranged, barrel-shaped parenchyma cells with no or little intercellular spaces. Each stomatal pore is surrounded by two guard cells that assist in stomatal opening driven by turgidity of guard cells. The guard cells are the only epidermal cells with unevenly thickened walls and chloroplasts. A root hair cell is a tubular unicellular extension of epiblema, the epidermis of root. It has a nucleus and large vacuole with lots of mitochondria in the cytoplasm and serves to absorb water and mineral salts by osmosis and active transport respectively. Trichomes are the hairy outgrowth of epidermis that may be unicellular or multicellular, live or dead and are mostly present on leaf surfaces.
