Expert Answer:

1. Apical Meristem:

  • Apical mersitem is Located at the growing points of the stem, roots, branches and in growing young leaves near the tips of stems and axillary buds.
  • It enables the root and stem to grow by increasing the length of plants.

2. Lateral Meristem:

  • It is present laterally (on the sides) on the roots and stem and is situated parallel to the longitudinal axis below the bark.
  • It is also found in vascular bundles of dicot roots and stems.
  • The girth and width or diameter or thickness of the stem or root increases due to the lateral meristem.

3. Intercalary Meristem:

  • It is located at internodes or stem regions between the places at which leaves attach, and at leaf bases, especially of certain monocotyledons.
  • The cells of the intercalary mersitem are active and continuously form a number of new cells.
