Meristematic Tissue

Meristematic tissues are further divided into two groups: apical meristem and cambium. Apical meristems are found at the tips of stems and roots. These cells increase the length of shoot and root, and are responsible for primary (first) growth. The cambium is of two kinds: vascular cambium and cork cambium. Vascular cambium produces two kinds of tissues: xylem, which is deposited central to the cambium, and phloem, which is deposited peripheral to the cambium. Cork cambium also produces two kinds of tissues: cork, which lies outside of the cork cambium, and phelloderm, which lies internal to it.
