Definition
Meristems are regions of undifferentiated plant cells that have the capacity for continuous division and growth, enabling the formation of new tissues and organs throughout the plant's life. They are primarily located at the tips of roots and shoots (apical meristems) and in the cambium layer (lateral meristems), contributing to primary and secondary growth.
Summary
Meristems are vital growth tissues in plants that allow for continuous cell division and the formation of new tissues. They are categorized into three main types: apical, lateral, and intercalary, each serving specific functions in plant growth and development. Apical meristems contribute to the lengthening of roots and shoots, while lateral meristems increase thickness, and intercalary meristems enable regrowth in certain species. Understanding meristems is crucial for various applications, including agriculture and plant breeding. By harnessing the knowledge of how meristems function, scientists and farmers can improve crop yields, enhance disease resistance, and promote sustainable practices. This foundational knowledge of plant growth is essential for anyone studying botany or working in related fields.
