The structure through which the leaf is attached to the stem is called?

• A. Petiole
• B. Leaf Base
• C. Lamina/Leaf Blade
• D. Venation

Answer: (B)

The attachment stalk is called the petiole. It connects the leaf blade to the stem at a node and carries the vascular tissues that transport water, minerals, and sugars between the stem and the leaf. The leaf base is the lower part of the leaf where it meets the stalk (or stem in sessile leaves), the lamina is the broad blade itself, and venation is the vein network within the blade. In most plants, the petiole is the correct term for the structure that holds the leaf and links it to the stem.
