The cork cambium is a several-cell-thick layer that is constantly dividing. Cambial cells are analogous to human stem cells, also constantly dividing and when given a signal, form specific tissues.

Adult greater peachtree borers are often mistaken for wasps, but they're actually clearwing moths. Greater peachtree borer larvae feed on the cambium tissue under the bark of stone fruit trees ...
