Which type of meristematic tissue is characterized by continuously dividing without losing its power of division?

The type of meristematic tissue characterized by continuously dividing without losing its power of division is eumeristems. Eumeristems, also known as primary meristems, are responsible for the growth of the plant and are found in areas such as the tips of roots and stems. They persist throughout the life of the plant, allowing for continuous growth and the ability to produce new tissues. This capability distinguishes them from other types of tissues that may divide for a limited period or only under certain conditions.

In contrast, pseudomeristems and meristemoids exhibit some limitations in their division capacity, as they may not maintain the same level of ongoing division as eumeristems. Pseudomeristems can be a form of tissue that resembles meristems but does not function in the same persistent manner. Meristemoids are specialized meristematic cells that can develop into new meristems but are often limited in their capacity and lifespan compared to eumeristems.

Periderms are not classified as meristematic tissue but rather serve a protective function, forming the outer layer of stems and roots in many woody plants. Understanding these distinctions is essential for grasping how different tissues function and contribute to plant growth and development.
