Final answer:
A typical mesophyll cell contains about 30 to 40 stomata.
Step-by-step explanation:
The epidermis of dicot leaves are layers of cells known as the mesophyll, or "middle leaf." The mesophyll typically contains two arrangements of parenchyma cells: the palisade parenchyma and spongy parenchyma. The palisade parenchyma has column-shaped, tightly packed cells, and may be present in one, two, or three layers.
The palisade parenchyma are loosely arranged cells of an irregular shape, which are the cells of the spongy parenchyma. The air space found between the spongy parenchyma cells allows gaseous exchange between the leaf and the outside atmosphere through the stomata. In summary, a typical mesophyll cell has about 30 to 40 stomata.
