Green expanded part of the leaf with veins and veinlets is called?

Explanation:
The broad, green, photosynthetic portion of the leaf is called the lamina, or leaf blade. This is the part that expands to form the flat surface where photosynthesis happens, and it contains the network of veins and veinlets. Venation refers to how those veins are arranged inside the blade, not to the blade itself. The stalk attaching the leaf is the petiole, and a pulvinus is a swollen joint at the base of some leaves used for movement—not the main blade. So the term that names the green expanded part with veins is lamina (leaf blade).
