Cambium

As seen in the picture, this tree stump seems as though it has different rings around it. These "layers" are a result of cambium being produced in the plant. This cambium is a certain type of tissue that comes in parallel rows of cells, which is why it seems as though the trunk of the tree is thickening. Sometimes cork will be overproduced in the stem of the plant and cracks and ridges will appear, as seen in the photo, allowing for gas to be exchanged between the air and the inside of the  stem.
