Figure 33.16 The Eudicot Leaf (A) This three-dimensional diagram shows a section of a eudicot leaf. (B) The network of fine veins in this maple leaf carries water to the mesophyll cells and carries photosynthetic products away from them. (C) Carbon dioxide enters the leaf through stomata like this one on the epidermis of a eudicot leaf. Trichomes are epidermal hairs that can break up airflow, reducing water loss from the leaf and repel water so that gas exchange can take place through the stomata.
