Explanation

Lateral meristems are cylinders of dividing cells. They are present in dicots and gymnosperms. Vascular and cork cambium are examples of the lateral meristem. They play an important role in the increase in diameter of stem and root and secondary growth are determinate i.e. they grow to a certain size and then stop e.g. leaves, lowers, and fruits; while others are indeterminate i.e. they- grow by meristems that continually replenish themselves, remaining youthful e.g. vegetative root and stem.
