Solution
The correct option is D Complimentary cells
The complementary cells is a mass of cells in plants formed from the cork cambium at the position of the lenticels. It is a group of loosely arranged cells that aid in gaseous exchange through cork. Lenticels are found on the stem of woody plants. Lenticels originate beneath stomata. As the lenticels formation starts, the parenchyma cells found near substomatal cavity lose their chlorophyll content and irregularly divide in different plants giving rise to a mass of colourless, rounded, thin walled, loosely arranged cells called as complementary cells.
Thus, the correct answer is option D.
