Lamina/Leaf Blade is the green expanded part of the leaf with veins.

• A. Venation
• B. Lamina/Leaf Blade
• C. Axillary Bud
• D. Nodes

Answer: (B)

The part of the leaf that is flattened, green, and carries the network of veins is the lamina, also called the leaf blade. This is the main photosynthetic surface of the leaf, providing a broad, flat area where light can be absorbed and chloroplasts can capture energy. The veins embedded in the lamina supply water and nutrients from the stem and help transport the sugars produced during photosynthesis.

Venation refers to the pattern and arrangement of those veins themselves, not the leaf tissue as a whole. An axillary bud sits at the junction between the leaf and the stem, not within the leaf blade. Nodes are the points along the stem where leaves or buds attach. So the green expanded part with veins is the lamina, or leaf blade.
