Compare the three types of meristems.
✓

Answer

There are total three types of meristems, they are:
  1. Apical meristem: These are situated at the growing tip of stem and roots, i.e., at shoot apex & root apex respectively. It is responsible for the growth or elongation of the root and stem, & it is called primary growth.
  2. Lateral meristem: These are found beneath the bark (called cork cambium) and in vascular bundle of dicot roots and stems (called vascular bundle). It is responsible for increase in girth, This is called secondary growth.
  3. Intercalary meristems: They are located at the base of leaves or internodes. It is responsible for the increase in the length of a leaves and internodes.
