bulliform cells help in folding up the monocotleaves but we see in some dicots also when the leaf becomes dry it fpldsupwards. How is it possible? please explain in detail.

❄️Bulliform cells are the large thin-walled, empty cells that occur in the epidermis of many grass leaves (monocots) These cells by their turgor pressure changes cause rolling and unrolling of the leaves, thus regulating water loss.
❄️When bulliform cells are flaccid, the leaves of grass close as the two sides of the blade fold up toward each other.
❄️Once adequate water is available, the leaves open again.
❄️When folded, the leaves are less exposed to sunlight, so they are heated less which prevents water loss.
In dicot leaves, bulliform cells are absent.
❄️They contain three types of cells in epidermis and these are- epidermal cells, guard cells, subsidiary cells.
❄️ When these cells also lose water, the leaf may fold but not as much as in case of monocot leaves containing bulliform cells.
❄️Thus, the bulliform cells is an specific future of monocots to prevent loss of water.
