Bulliform cell

Bulliform cells or motor cells are large, bubble-shaped epidermal cells that occur in groups on the upper surface of the leaves of many monocots. These cells are present on the upper surface of the leaf. They are generally present near the mid-vein portion of the leaf and are large, empty and colourless. They are proposed, though not confirmed, to be involved in folding and unfolding of leaf tissue in order to control light intensity and reduce overall water loss.
