Meristematic Tissue: They are the group of young cells, which consists of actively dividing cells and leads to increase in length and thickness of the plant. There are different types of meristematic tissues, which are classified on the basis of positions, functions, plane of divisions, origin and development. The three main types of meristematic tissues depending on the occurrence of the meristematic tissue on the plant body are
1. Apical Meristem.
2. Lateral Meristem.
3. Intercalary Meristem.
Functions of Meristematic Tissue
1. It is responsible for the growth of the new organs.
2. Involved in the movement of water and nutrition within the plants.
3. These tissues are responsible for both primary and secondary growth of the plant.
4. It is the outermost tissue, functions by providing protection from mechanical injury.
5. It gives rise to the epidermis layer, cortex, endodermis, ground tissue and vascular tissue.

Meristematic Tissue
Meristematic tissue is a type of plant tissue that is responsible for growth and development in plants. It is composed of cells that are capable of cell division, which plays a crucial role in increasing the length and girth of the plant.
Characteristics of Meristematic Tissue:
Meristematic tissue exhibits the following characteristics:
1. Cell Division: The cells in meristematic tissue are actively dividing and are responsible for the growth of the plant.
2. Small and Isodiametric Cells: The cells in meristematic tissue are small and isodiametric, meaning they are roughly spherical in shape. This allows for easy division and growth.
3. Thin Cell Walls: The cell walls in meristematic tissue are thin, allowing for flexibility and expansion during growth.
4. Large Nucleus: The cells in meristematic tissue have large nuclei, which contain the genetic material necessary for cell division and growth.
Types of Meristematic Tissue:
There are two main types of meristematic tissue:
1. Apical Meristem: Located at the tips of roots and stems, apical meristem is responsible for primary growth, which leads to an increase in the length of the plant.
2. Lateral Meristem: Found in the cambium layer of the plant, lateral meristem is responsible for secondary growth, which leads to an increase in the girth or thickness of the plant.
Importance of Meristematic Tissue:
Meristematic tissue plays a crucial role in plant growth and development. It allows the plant to increase in length and girth, enabling it to reach its full potential. The continuous division of cells in meristematic tissue leads to the formation of new tissues, which perform specific functions in the plant.
Overall, meristematic tissue is composed of cells that are capable of cell division, making option B the correct answer to the given question.
