Meristem
The meristem is a type of tissue found in plants. It consists of undifferentiated cells (meristematic cells) capable of cell division. Cells in the meristem can develop into all the other tissues and organs that occur in plants. These cells continue to divide until a time when they get differentiated and then lose the ability to divide. Differentiated plant cells generally cannot divide or produce cells of a different type. Meristematic cells are undifferentiated or incompletely differentiated. They are totipotent and capable of continued cell division. Division of meristematic cells provides new cells for expansion and differentiation of tissues and the initiation of new organs, providing the basic structure of the plant body. The cells are small, with small vacuoles or none, and protoplasm filling the cell completely. The plastids (chloroplasts or chromoplasts), are undifferentiated, but are present in rudimentary form (proplastids). Meristematic cells are packed closely together without intercellular spaces. The cell wall is a very thin primary cell wall. The term meristem was first used in 1858 by Carl Wilhelm von Nägeli (1817–1891) in his book Beiträge zur Wissenschaftlichen Botanik ("Contributions to Scientific Botany"). It is derived from the Greek word merizein (μερίζειν), meaning to divide, in recognition of its inherent function.There are three types of meristematic tissues: apical (at the tips), intercalary or basal (in the middle), and lateral (at the sides). At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone. Cells of this zone have a stem cell function and are essential for meristem maintenance. The proliferation and growth rates at the meristem summit usually differ considerably from those at the periphery.

meristem
Meristem is a type of plant tissue that consists of undifferentiated cells which retain the ability to divide and generate new cells and tissues. It is the region of active cell division and growth in plants, and is responsible for the plant's increase in size and formation of new organs such as leaves, flowers, and roots. There are three types of meristem: apical, lateral and intercalary.
Webster Dictionary
Meristemnoun
a tissue of growing cells, or cells capable of further division

Meristem
A meristem is the tissue in most plants consisting of undifferentiated cells, found in zones of the plant where growth can take place. The meristematic cells give rise to various organs of the plant, and keeps the plant growing. The Shoot Apical Meristem gives rise to organs like the leaves and flowers. The cells of the apical meristems - SAM and RAM - divide rapidly and are considered to be indeterminate, in that they do not possess any defined end fate. In that sense, the meristematic cells are frequently compared to the stem cells in animals, which have an analogous behavior and function. The term meristem was first used in 1858 by Karl Wilhelm von Nägeli in his book Beiträge zur Wissenschaftlichen Botanik. It is derived from the Greek word merizein, meaning to divide, in recognition of its inherent function. In general, differentiated plant cells cannot divide or produce cells of a different type. Therefore, cell division in the meristem is required to provide new cells for expansion and differentiation of tissues and initiation of new organs, providing the basic structure of the plant body. Meristematic cells are incompletely or not at all differentiated, and are capable of continued cellular division. Furthermore, the cells are small and protoplasm fills the cell completely. The vacuoles are extremely small. The cytoplasm does not contain differentiated plastids, although they are present in rudimentary form. Meristematic cells are packed closely together without intercellular cavities. The cell wall is a very thin primary cell wall.
Chambers 20th Century Dictionary
Meristem
mer′is-tem, n. the formative tissue of plants, distinguished from the permanent tissues by the power its cells have of dividing and forming new cells.—adj. Meristemat′ic. [Gr. meristos, verbal adj. of merizein, to divide—meros, a part.]
U.S. National Library of Medicine
Meristem
A group of plant cells that are capable of dividing infinitely and whose main function is the production of new growth at the growing tip of a root or stem. (From Concise Dictionary of Biology, 1990)
