Detailed explanation-1: -Meristematic tissues are present at the tip of the stem and the roots in plants which are the sites of active growth. They undergo rapid cell division resulting in the growth of the plants.

Detailed explanation-2: -Meristems are regions in plants in which mitosis takes place.

Detailed explanation-3: -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-4: -The meristematic tissues, or simply meristems, are tissues in which the cells remain forever young and divide actively throughout the life of the plant. The different types of meristems are apical, lateral and intercalary meristems.

Detailed explanation-5: -Depending on the occurrence of the meristematic tissue on the plant body, we can classify the meristems into three types. They are: (Source: BiologyDiscussion) Apical Meristems – These meristems are located on the tip of the root, stem etc. They help in the growth of the root system as well as the shoot system.
