Open in App
Solution
The correct option is B subsidiary cells
Stomata are the openings present on the epidermis of the leaves. They regulate transpiration and gaseous exchange. The stomatal apparatus is formed of the stomatal pore, two guard cells and subsidiary cells (specialized epidermal cells).
Bulliform cells are found in grasses. They are enlarged, empty, colourless, modified parenchymatous epidermal cells along the veins on the upper surface of the leaf. These cells regulate the exposure of the leaf surface to minimise the water losses.
Lenticels are the pores in the stem of a woody plant. It permits the gaseous exchange between the atmosphere and the internal tissues.
Complementary cells are a group of cells that are formed from the cork cambium around the location of lenticels. They aid in gaseous exchange through the cork.
