Meristematic tissue, often referred to as meristem, is a type of plant tissue characterized by its ability to divide and differentiate into various types of permanent tissues. It plays a crucial role in the growth and development of plants. Meristematic tissue is found in the tips of roots, shoots, and buds, as well as in the vascular bundles of stems and leaves. There are three main types of meristematic tissue: apical meristem, lateral meristem, and intercalary meristem.

Apical meristem is located at the tips of roots and shoots, and it is responsible for the primary growth of plants. Lateral meristem, also known as the cork cambium, is found between the xylem and phloem in the vascular bundles of stems and roots. It contributes to the secondary growth of plants, increasing the plant's diameter. Intercalary meristem is found in the internodes of grasses and some other plants. It is responsible for the elongation of internodes, allowing the plant to grow taller.

Meristematic tissue is undifferentiated, meaning it does not have a specific function or structure. Instead, it has the potential to differentiate into various types of permanent tissues, such as epidermis, cortex, and vascular tissues. This ability to differentiate is what allows meristematic tissue to contribute to the growth and development of plants.

Meristematic tissue is essential for the survival and reproduction of plants. It allows plants to grow and adapt to their environment, and it is responsible for the production of new leaves, flowers, and fruits. Without meristematic tissue, plants would not be able to grow and reproduce, and they would eventually die.
