A tissue of growing cells, or cells capable of further division.
Any growing point of both root and stem on a plant, where active cell division is taking place. There are both apical and axillary meristems.
Technically, the actively dividing cell tissue taken from root tips and from the tips of new growths or floral shoots; sometimes loosely used to refer to the mericlone plant that is produced from the laboratory propagation of meristem tissue.
A meristem is a plant tissue usually made up of small cells that are capable of dividing indefinitely and give rise to similar cells or cells that differentiate into definitive tissues and organs (flowers).
Embryonic tissue; undifferentiated, growing actively dividing cells
Cells at the growing tips of stems or roots that are dividing and are undifferentiated but later become different parts of the plant. Region of actively dividing cells in plants.
Gr. meristos: divided] • Plant tissue made up of actively dividing cells.
regions of the plant body where active mitosis and cell division occurs. Meristems are located at the tips of shoots and roots. Meristematic tissues are alsopresent in the vascular cambium of woody stems and in expanding leaves.
An undifferentiated cell population that resides at the growing tip of the roots or shoots of a plant.
Localised region of active cell-divisions in plants from which permanent tissue is derived. The principal meristems occur at the tips of stems and roots.
A plant cell line capable of continuous cell division, such as cambium in the stem or pericycle in the root
the growing part of a plant where permanent tissues is derived.
An organized group of dividing cells whose derivatives give rise to the tissues and organs of a flowering plant. Key examples are the root apical meristem and shoot apical meristem.
A part of a plant in which cell division is concentrated (especially the shoot apices, lateral buds and a zone near the tips of roots and rootlets).
A localised region of active cell division. Apical meristems are found at the tips of stems and roots. The lateral meristem (cambium) is found just under the bark in trees.
Mass of undifferentiated cells which divide actively, situated at the tip of buds or roots, at the origin of organs. Meristem is free of virus.
The region of active cell division in plants, from which permanent tissue is derived. adj. meristematic
a formative plant tissue specialised in dividing indefinitely to give rise to new cells that then differentiate into definitive tissues and organs.
undifferentiated tissue from which new cells are formed, as at the tip of a stem or root
a parenchyma cell that has the ability to divide and differentiate
a region of undifferentiated cells from which new cells arise through cellular division
a tissue that contains cells which have the capacity to divide to make new cells
(or shoot apex meristem) - growing tip of a plant, usually dome shaped, around which primordia are initiated.
Portion of a thallus where the cells are able to divide and produce new growth
lip of plant growth, branch lip.
Undifferentiated tissue that is capable of developing into specialized tissue such as toot, leaf or stem. In orchids, a plant produced by culturing meristematic tissue.
tissue capable of dividing to form new cells.
region of totipotent cells in which cell division and initiation of tissues and organs takes place; see apical meristem, vascular cambium and cork cambium
A region of a plant in which active cell division occurs, the cells of the meristem being undifferentiated into a specialized form. Meristematic tissues occur at the root and shoot tips giving growth in length.
The tip of a growing plant shoot or root.
( mare-eh-stem) [Gk. merizein, to divide] Plant tissue that remains embryonic as long as the plant lives, allowing for indeterminate growth.
Areas of plants that contain actively dividing cells
Areas of actively dividing cells and plant growth; capable of developing into specialized tissues.
growing regions of a plant in which cells that have retained their embryonic characteristics, or have reverted to them secondarily, divide to produce new cells.
an organized, undifferentiated plant tissue with rapidly dividing cells that differentiate to form new tissues or organs
the region of rapidly dividing cells of one of the growing points of a plant that further differentiate to produce shoots, roots, and flowers.
Undifferentiated cell capable of developing into a number of organs and/or tissues; a growing point.
Localised region of active cell division in plants
The actively growing tissue of a plant, used for artificial cloning.
( mér'-e-stem) - Plant tissue in the process of formation; vegetative cells in a state of active division and growth, e.g., those at the apex of growing-stems and roots.
The actively growing area of the plant from which mature tissues such as leaf, stems, flowers and roots originate.
A group of localised, dividing cells, which produce active growth; this could occur either at the root and shoot tips or in the trunk (lateral growth).
Group of undifferentiated cells from which new tissues are produced. Most plants have apical meristems which give rise to the primary tissues of plants, and some have secondary meristems which add wood or bark.
The region of active cell-division in plants. The cells so formed then become modified to form the various tissues such as the epidermis and cortex.
The meristem is a group of plant cells that can divide indefinitely. The meristem provides new cells for the plant.
A meristem is a tissue in plants consisting of undifferentiated cells (meristematic cells) and found in zones of the plant where growth can take place - the roots and shoots.
