A meristem is the tissue in most plants containing undifferentiated cells, found in zones of the plant where growth can take place. Meristematic cells give rise to various organs of the plant and keep the plant growing.hese secondary meristems are also known as lateral meristems because they are involved in lateral growth. At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone.
meristem. n. 1. (Botany) a plant tissue responsible for growth, whose cells divide and differentiate to form the tissues and organs of the plant. Meristems occur within the stem (see cambium) and leaves and at the tips of stems and roots.  Best Answer: Meristems are tissues within a plant that are undifferentiated-that is, they have no defined identity like being leaf tissue or stem tissue. Meristems are the location of growth for plants including the root, base of roots, stems, flowers, and leaves. There are specific names for these types of meristems. For example, root (or shoot or floral) apical meristem and basal meristem. There are two major types of meristems: primary and secondary. Primary meristems are tissues that make the plant taller, or a plant's appendages (e.g. branches) grow longer A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. Meristematic cells give rise to various organs of the plant and keep the plant growing. These secondary meristems are also known as lateral meristems because they are involved in lateral growth. At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone. Cells in the meristem, however, divide and produce all of the new cells in a plant. While meristem tissue is the source of the regenerative potential of a plant, meristems also play a pivotal role in normal plant growth. Plants have the unique ability to continue to grow and develop new organs while functioning as a mature, reproducing organism. Both roots and shoots have meristematic tissue at their tips called apical meristems that are responsible for the lengthening of roots and shoots. The shoot apical meristem is formed during embryonic development, but after germination gives rise to the stem, leaves, and flowers. Apical meristem is found at the apices, or tips of the plant, both the tip of the shoot and the root and is a region of actively dividing cells. The definition of is easy to remember when you break it down. An apex (plural: apices) is the tip, the very end, of something.  While some of the cells of the apical meristem divide to generate new meristematic cells, most of the offspring cells differentiate into specialized cell types that stop dividing and function as a part of the organ in which they were generated. Both roots and shoots have meristematic tissue at their tips called apical meristems that are responsible for the lengthening of roots and shoots. The shoot apical meristem is formed during embryonic development, but after germination gives rise to the stem, leaves, and flowers. The apical meristem, or growing tip, is a completely undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to begin growth of new cells in young seedlings at the tips of roots and shoots (forming buds, among other things). The primary meristems in turn produce the two secondary meristem types. These secondary meristems are also known as lateral meristems because they are involved in lateral growth. At the meristem summit there is a small group of slowly dividing cells which is commonly called the central zone. The primary meristems in turn produce the two secondary meristem types. These secondary meristems are also known as lateral meristems because they are involved in lateral growth. 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 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. These secondary meristems are also known as lateral meristems because they are involved in lateral growth. At the meristem summit, there is a small group of slowly dividing cells, which is commonly called the central zone.
