kambiumlagen

Kambiumlagen, often referred to as cambium, is a vital plant tissue responsible for secondary growth. It is a type of meristematic tissue, meaning its cells are capable of division and differentiation. There are two primary types of cambium found in plants: vascular cambium and cork cambium. Vascular cambium is located between the xylem and phloem in the stems and roots of dicotyledonous plants and gymnosperms. Its cell divisions produce new xylem towards the inside and new phloem towards the outside. This process leads to an increase in the girth or diameter of the plant organ, forming wood and bark. Cork cambium, also known as phellogen, originates in the outer cortex or phloem. It produces cork cells (phellem) to the outside, which are protective, waterproof cells, and a layer of phelloderm to the inside. This secondary growth in thickness contributes to the formation of the periderm, which replaces the epidermis in woody stems and roots. The activity of cambium is often influenced by environmental factors such as season and temperature, leading to the formation of annual growth rings in trees.
