The plant tissue composed of totipotent cells that allows plant growth
A tissue of growing cells, or cells capable of further division
In plants, region of cells capable of division and growth. Meristems are classified by location as apical, or primary (at root and shoot tips), lateral, or secondary (in the vascular cambium and cork cambium), or intercalary (at internodes, stem regions between the places at which leaves attach, and at leaf bases, especially in certain monocots, e.g., grasses). Apical meristems give rise to the primary plant body. Lateral meristems provide increase in stem girth. Injured tissues can convert other cells to new meristem for wound healing
the region of rapidly expanding cells of one of the growing points of a plant that further differentiate to produce shoots, roots, and flowers
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
1 A plant tissue composed of dividing cells and giving rise to organs such as leaves, flowers, xylem, phloem, roots 2 A region of a plant in which cells are not fully differentiated and are capable of repeated mitotic divisions
growing points of grasses, from which leaf blade elongation occurs during active growing periods
undifferentiated tissue from which new cells are formed, as at the tip of a stem or root
the zone of active cell division in a plant
{i} area of cellular division, embryonic tissue (Botany)
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
Region of active growth in a wine, made up of meristematic cells which divide to form new cells during growth
Vegetal tissue formed of undifferentiated cells and located in growth plant areas where are many and quickly cellular divisions ; meristem culture beginning from an apical meristem (0 2 to 0 4 mm) is an " in vitro " technique for vegetative multiplication
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 [CUB]
A small group of cells that retain the capacity for rapid cell division (growth) The main meristematic areas within the plant are the apical meristems of the terminal and lateral shoots, the vascular cambium, the root apex, and the marginal meristems (active during the growth of leaves)
Localised region of active cell division in plants
A specialized area within a plant where cell division occurs very rapidly Lateral meristems, for example, exist near root and shoot tips to facilitate cell division and, hence, vertical plant growth
Embryonic tissue in plant, which allows for indeterminate growth
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)
undifferentiated tissue made up of cells that divide to form specialized tissues and organs
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)
