Cork is the outer layer or bark from an evergreen oak tree (Quercus suber). The tree can live for 150/250 years in nature and reach 20m in height. The first cork is harvested when the tree is about 25 years old and it takes 12 more years before another harvest can be taken. In all a cork tree can be harvested some 12 times before it has to be cut down and a new sapling tree planted.

It's the inner bark of the cork tree. I think it's a type of oak. Ferdinand the Bull sat under a cork tree to smell flowers. The illustration in the children's book shows corks hanging on the tree like apples, but in reality the bark is peeled off and individual corks are punched out.

cork is the technical name of the layer of woody plants we call bark. As the tree grows in girth (gets wider), its layer of Xylem and Phloem (the vascular system that carries water and nutrients from the soil up to the shoot system and sugar and amino acids down to the root system) continuously move outward. On the outer most edge of this layer of vascular tissue, cork is being made and pushing the old cork off the tree (thats why bark falls off the tree or is easily pulled off in some cases). Every year these vascular systems move further outward and leave rings where they once were active before, making the tree rings we use to estimate the age of fallen trees. Thats also why when you cut a ring around a tree, it dies, because you also cut the vascular system and the cork cambium out.

Itis a plant product. Actually it is made out of the bark of a tree which grows mainly in Portugal. Portugal is the main source of this product in the world supplying about 90% of the world's requirement

cork comes from a certain kind of tree. So I guess the answer is plant.

cork is a plant product obtained from the secondary growth resultant wood . NOt an anomal product at all.

I agree with Hans B, cork is produced in woody plants by the cork cambium, which divides to produce parenchyma cells and dead cork cells. These are hollow, with thick, lignified (woody) walls, and form bark. But yes, it also refers to 'Quercus suber', the cork oak tree.
