Vedclass · Answer

(B) The correct answer is $B$. The epidermal surface of the leaf exhibits $1,000$ to $60,000$ minute openings called stomata.Stomata are bordered by two specialized epidermal cells,known as guard cells.In many plants,these guard cells are accompanied by specialized cells called subsidiary cells,but this is not a universal rule.Guard cells possess chloroplasts and mitochondria.The walls of guard cells are unevenly thickened; specifically,the inner walls (facing the stomatal aperture) are thick and inelastic,while the outer walls are thin and elastic.Therefore,the statement that guard cells are always surrounded by subsidiary cells is incorrect.
