 Cambium is layer or layers of tissue, also known as lateral meristems, that are the source of cells for secondary growth. There are two types of cambium - Cork cambium & vascular cambium.


Apical meristem is a meristem at the tip of a plant shoot or root that causes the shoot or root to increase in length = primary growth.

The apical meristem, or growing tip, is a completely undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to begin growth of new cells in young seedlings at the tips of roots and shoots (forming buds, among other things). Specifically, an active apical meristem lays down a growing root or shoot behind itself, pushing itself forward. Apical meristems are very small, compared to the cylinder-shaped lateral meristems

There are two types of secondary meristems, these are also called the lateral meristems because they surround the established stem of a plant and cause it to grow laterally (i.e., larger in diameter).

  • Vascular cambium, which produces secondary xylem and secondary phloem. This is a process that may continue throughout the life of the plant. This is what gives rise to wood in plants. Such plants are called arborescent. This does not occur in plants that do not go through secondary growth (known as herbaceous plants).
  • Cork cambium, which gives rise to the periderm, which replaces the epidermis.
hope u got it dear
