What is the primary function of intercalary meristem in plants?

The primary function of intercalary meristem in plants is to facilitate growth at specific locations, particularly at the base of grass leaves and in some other monocots. This type of meristem is located between mature tissues and allows for the elongation of leaves and stems after being grazed or cut, which is vital for the survival and continued growth of grass species. The intercalary meristem enables these plants to quickly recover and regenerate, enhancing their adaptability to their environment. Therefore, its role is essential in the growth processes of grass, contributing to their ability to sustain themselves in disturbed conditions.
