answered-by-expert Expert Answer
Lateral meristems - It is the meristem that occurs laterally, parallel to the long axis of plant body. Cambium strips formed in the vascular bundles and in the cortex are common examples of lateral meristem. It is responsible for an increase in the girth (circumference) of the plant body as it brings about the formation of secondary permanent tissues.
 
Intercalary meristems - It is the meristem that occurs between permanent tissues. It represents the remnant of the apical meristem. It is particularly common at the nodal regions. It may also occur at the base of the leaves. The intercalary meristem also contributes towards the increase in length as it brings about elongation of the internodal regions.
