Cambium

This is a picture of a tree. Cambium can be found in woody plants, such as the tree above. Cambium is a group of meristem cells. Meristem cells are like the equivalent to human stem cells, which are undifferentiated cells. There are two types of cambium: vascular cambium and cork cambium. The main job of vascular cambium is to give rise to xylem and phloem cells. Xylem forms the interior wood of woody plants and carries water and some nutrients from the soil to other parts of the plant. Phloem develops exterior to the cambium, forming bark, and carries nutrients, like sugar, through the plant for producing energy. Cork cambium produces cork, a part of the bark, and protects the tissue underneath.
