Meristems are specialized groups of plant cells that are responsible for active cell division and growth. Some of the key characteristics of meristems are:
1. Cell division: Meristems have a high rate of cell division, which allows for continuous growth and development in plants.
2. Undifferentiated cells: Cells in meristems are undifferentiated, meaning they are not yet specialized for specific functions. This allows them to give rise to various types of specialized cells and tissues.
3. Small and compact: Meristems are small and compact clusters of cells located at the tips of roots and shoots, as well as in other regions of plant bodies.
4. Rapid growth: Meristems enable rapid growth and elongation of roots and shoots, allowing plants to increase in size.
5. Tissue establishment: Meristems play a crucial role in establishing and maintaining the primary and secondary tissues of plants. Primary meristems are responsible for the formation of primary tissues that make up the plant body, while secondary meristems are involved in the production of secondary tissues like bark and wood.
6. Indeterminate growth: Meristems have the ability to undergo indeterminate growth, meaning they can continue to divide and generate new cells throughout the life of a plant. This contributes to the continuous growth of plants in length and girth.
7. Localization: Meristems are primarily located at the apical tips (apical meristems) and lateral regions (lateral meristems) of the plant. Apical meristems drive the growth of roots and shoots, while lateral meristems contribute to the growth in thickness through the production of secondary tissues.
Overall, meristems are fundamental to plant growth and development, as they provide a continuous source of new cells that can differentiate into different types of tissues and organs.
