The correct option is
A A- 5, B- 1, C- 2, D- 3
A) The innermost distinct layer of cells of cortex in roots of dicotyledonous plants is known as endodermis. It consists of a single layer of barrel-shaped cells without any intercellular spaces. There are depositions of water impermeable, waxy suberin in the form of Casparian strips in the walls of the endodermal cells. Passage cells are endodermal cells of older roots which have retained thin walls and Casparian strips rather than becoming waterproof like the other cells around them.
B) The mass of cells formed from the cork cambium at the position of the lenticels is called complementary cells. Lenticels are pores present in the stem of woody plants that allow gas exchange between the atmosphere and the internal tissues.
C) There are certain epidermal cells in monocot leaves along the veins that modify themselves into large, empty, colorless cells. These are called bulliform or motor cells. When the water supply is sufficient for the plant, the bulliform cells absorb water and become turgid. This causes the leaf to straighten up and become exposed.
D) The epidermal tissue system forms the outer most covering of the whole plant body and comprises epidermal cells, stomata, and epidermal appendages. Stomata are structures present in the epidermis of leaves. Each stoma is composed of two bean-shaped cells known as guard cells. Sometimes, a few epidermal cells, in the vicinity of the guard cells become specialized in their shape and size and are called subsidiary cells.
Hence, the correct match is A- 5, B- 1, C- 2, D- 3.
