The Cork Oak Tree is an evergreen medium-sized oak that has a thick corky bark, periodically harvested to produce marketable cork. So, cork is a natural raw material grown around the trunk of the tree, its bark actually!

Is cork made of plant cells?

Cork or cork cambium (pl. ... Taken a more cursory look, cork cambium is one of the meristematic tissues of a plant which are a series of tissues that consist of some incompletely differentiated cells from which the plant grows. Its function is to produce cork which is a strong protective material.

How is cork produced?

Cork is composed of dead cells that accumulate on the outer surface of the cork oak tree. Harvests occur at nine-year intervals, when the cork layer reaches a thickness of 1-2 in 12-5 cm). The harvest from a young tree yields about 35 lb (16 kg) of cork, while the yield for an older tree may be 500 lb (225 kg).

What tree produces cork?

The Cork Oak Tree is found in the Mediterranean (Spain and Portugal.) Laws dictate that a tree must grow for 25-34 years before the first harvest. This is done by a person called an extractor and it is done in a special way to make sure the tree can continue to grow and produce more cork.

What type of tissue is cork?

A cork cambium is a type of meristematic tissue in many vascular plants. It is in particular a lateral meristem, which is a meristem that is concerned with the lateral growth of plants.

Where is cork found in plants?

Cork cambium (pl. cambia or cambiums) is a Cell found in many vascular plants as a part of the epidermis. It is one of the many layers of bark, between the cork and primary phloem. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.

What is natural cork?

Cork is the outer bark of the cork oak tree (Quercus suber L.). 100 percent natural, reusable and recyclable, cork is, whether from the environmental, social or economic perspectives, one of the world's most versatile materials.

What is cork in chemistry?

Cork is an impermeable buoyant material, the phellem layer of bark tissue that is harvested for commercial use primarily from Quercus suber (the cork oak), which is native to southwest Europe and northwest Africa. Cork is composed of suberin, a hydrophobic substance.

Where do cork oaks grow?

Cork oak is found through southwestern Europe and into northwestern Africa in Portugal, Spain, France, Italy, Algeria, Morocco and Tunisia.
