Detailed explanation-1: -The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc. These cells help to increase the length and girth of the plant.

Detailed explanation-2: -Meristems at the tips of roots provide a constant supply of new cells allowing roots to grow longer. Meristems at the tips of shoots allow a plant to keep growing taller and spread wider. Meristems between the xylem and phloem increase the width of a plant. These result in the annual growth rings in trees.

Detailed explanation-3: -Plants develop new organs (stems, leaves, flowers, roots) via cell division and cell differentiation. Because the source of all new cells in a plant is the meristem, this tissue plays an important role in organ development as well.

Detailed explanation-4: -Meristematic cells have the ability to divide continuously and help in the growth of plants. After the growth is complete, cells formed by the division of meristematic cells lose their ability to divide and start to perform a specific function.

Detailed explanation-5: -Meristematic tissues are responsible for plant growth. They are present at the tips of roots, stem and branches. The cells present in these tissues constantly divide to produce new cells. The cells actively divide to produce new cells. Meristematic cells may be intercalary as in case of monocots.
