the cork oak. I have seen these trees myself and it does not produce it as a fruit or seed. It is the outside part of the wood that is cork at the thick part of the tree. In the related box below, I posted the wikipedia article on the cork oak. It has pictures and everything you need to now.
Cork is a part of the bark on a Cork Oak Tree.
The type of tree that produces large pods is called a "mesquite tree."
Cork is the type of tree bark of which Portugal is known as the world's leading exporter. Specifically, Portugal produces over 50 percent of the world's cork from the cork oak [Quercus suber]. Around 720,000 hectares [2,780 square miles; 7,200 square kilometers] are dedicated to cork oak cultivation.The Algarve Region in southern Portugal is famous for its superior quality of cork oak trees. North of the Algarve, the Alentejo Region also is prime area for cork oaks.
The type of tree that produces dark blue berries is the blueberry tree.
The type of tree that produces large bean pods is called a "mesquite tree."
The type of tree that produces long seed pods is called a "locust tree."
Cork tissue is formed from the outer layer of the cork oak tree, primarily through the activity of cork cambium, a type of lateral meristem. This cambium produces cork cells, which are dead, hollow cells filled with air, providing insulation and protection. These cells are rich in suberin, a waxy substance that helps prevent water loss and protects against pests and diseases. Over time, layers of cork cells accumulate, forming the characteristic bark of the tree.
The type of tree that produces long, flat seed pods is called a catalpa tree.
The tree that produces bean-like pods is called a mesquite tree.
The tree that produces brown seed pods is typically a mesquite tree.
The tree that produces pea-like pods is called the acacia tree.
Cork comes from a cork tree :]
