Question

While observing a temporary mount of leaf peel under microscope compare the size of epidermal cells and guard cells

Answer 1

The plant epidermis is a multi functional tissue playing important roles in water relations, defense, and pollinator attraction, while guard cells are located in the leaf epidermis and pairwise surround stomatal pores, which allow CO2 influx for photosynthetic carbon fixation and water loss via transpiration to the atmosphere.
