What is the definition of meristematic tissue?

  Meristematic tissue is a type of plant tissue that is responsible for the growth and development of the plant. It is characterized by its ability to divide throughout the life of the plant and is found in certain areas of the plant, including the tips of roots and shoots, and in areas where new growth is occurring. This tissue is responsible for the production of new cells, which allows the plant to grow and develop. As cells in the meristematic tissue divide, they differentiate into other types of cells, such as those that make up the plant's leaves, stems, and roots.
