Apical meristem
The apical meristem is responsible for the lengthening of the plant. It is a type of meristematic tissue located at the tips of stems and roots in plants. Meristematic tissues are responsible for the growth and development of plants.

Meristematic Tissues
Meristematic tissues are found in regions of the plant where active growth occurs. They are responsible for producing new cells and are characterized by their ability to divide rapidly. The three types of meristematic tissues in plants are apical meristem, lateral meristem, and intercalary meristem.

Apical Meristem
The apical meristem is located at the tips of stems and roots. It is responsible for the primary growth of the plant, which includes the lengthening of the stem and root. The cells in the apical meristem divide rapidly, producing new cells that differentiate into various types of tissues. The division of cells in the apical meristem pushes the growing tip of the plant forward, allowing it to grow in length.

Functions of Apical Meristem
The apical meristem performs several important functions in the plant:

1. Primary Growth: The apical meristem is responsible for the primary growth of the plant, which involves the lengthening of the stem and root.

2. Cell Differentiation: The cells produced by the apical meristem differentiate into various types of tissues, such as vascular tissues, epidermis, and ground tissues.

3. Formation of New Organs: The apical meristem gives rise to new organs, such as leaves, flowers, and lateral branches.

4. Protection: The apical meristem is protected by a layer of cells called the root cap or shoot apical meristem, which helps protect the meristem from damage as the plant grows.

Conclusion
In conclusion, the apical meristem is responsible for the lengthening of the plant. It is a type of meristematic tissue located at the tips of stems and roots. The cells in the apical meristem divide rapidly, producing new cells that differentiate into various types of tissues. The apical meristem performs several important functions, including primary growth, cell differentiation, formation of new organs, and protection.
