(A) Bulliform cells → (iv) Isobilateral leaf: Bulliform cells are specialized, large epidermal cells found in the leaves of many monocots (which typically have isobilateral leaves). They help the leaves roll or unroll to minimize water loss.
(B) Guard cells → (i) Stomata: Guard cells are pairs of specialized epidermal cells that surround and regulate the opening and closing of the stomatal pore for gas exchange.
(C) Casparian bands → (ii) Endodermis: Casparian bands (or strips) are water-impermeable waxy layers found in the radial and transverse walls of endodermal cells in plant roots.
(D) Subsidiary cell → (iii) Accessory cells: Subsidiary cells are specialized epidermal cells that surround guard cells and provide them with mechanical and physiological support; they are also known as accessory cells.
