Lateral meristem occurs on the sides and takes part in increasing girth of the plant. Intra fascicular cambium is the primary lateral meristem which lies in vascular bundles of dicot and gymnosperm stems in between phloem and xylem. Examples of secondary lateral meristems are vascular cambium of the root, inter fascicular cambium of stem,cork cambium etc. that take part in the secondary growth.

Definition of Lateral Meristem:
Lateral meristems are regions of actively dividing cells that are responsible for the secondary growth in plants. They are found in the vascular cambium and cork cambium.
Explanation:
Vascular Cambium:
- The vascular cambium is a type of lateral meristem that is responsible for the secondary growth in dicot plants.
- It is a thin layer of meristematic tissue located between the xylem and phloem in the vascular bundles of stems and roots.
- The vascular cambium produces secondary xylem (wood) towards the inside and secondary phloem towards the outside, contributing to the increase in girth of the plant.
Cork Cambium:
- The cork cambium, also known as phellogen, is another type of lateral meristem that is responsible for the formation of the outer bark in woody plants.
- It is a meristematic tissue that produces cork cells towards the outside and phelloderm cells towards the inside.
- The cork cambium helps protect the plant from mechanical damage, pathogens, and water loss.
Conclusion:
In conclusion, vascular cambium and cork cambium are both examples of lateral meristems that play important roles in the secondary growth of plants. They are responsible for the increase in girth and the formation of bark in woody plants.
