Question:

Explain the function and location of lateral meristems in plants.

Answer:

Lateral meristems, comprising the vascular cambium and cork cambium, are responsible for the secondary growth of plants, which refers to the increase in girth or thickness. These meristems are located along the sides of stems and roots. The vascular cambium adds layers of vascular tissue called secondary xylem (wood) and secondary phloem, contributing to the thickening of stems and roots. This is particularly evident in woody plants where the production of new layers of wood each year results in the formation of tree rings.
