Vedclass · Answer

(D) The correct statements are $I, II, III,$ and $IV$. Statement $V$ is incorrect because the shapes are reversed.$I.$ Epidermal cells are elongated,compactly arranged,and possess a small amount of cytoplasm with a large central vacuole.$II.$ The epidermis is often covered with a waxy,thick layer called the cuticle,which prevents water loss. This layer is absent in roots.$III.$ Root hairs are unicellular elongations of epidermal cells that help in water absorption. Trichomes (stem hairs) are multicellular elongations of the epidermis that help in preventing water loss.$IV.$ Trichomes can be branched or unbranched,soft or stiff,and may be secretory or help in preventing transpiration.$V.$ In grasses (monocots),guard cells are dumb-bell-shaped,whereas in dicots (e.g.,bean,pea),they are bean or kidney-shaped. Since the statement claims the opposite,it is incorrect.
