mer·i·stem

 (mĕr′ĭ-stĕm′)
n.
The undifferentiated plant tissue from which new cells are formed, as that at the tip of a stem or root.

[Greek meristos, divided (from merizein, to divide, from meris, division; see (s)mer- in Indo-European roots) + -em (as in xylem phloem).]

mer′i·ste·mat′ic (-stə-măt′ĭk) adj.
mer′i·ste·mat′i·cal·ly adv.

meristem

(ˈmɛrɪˌstɛm)
n
(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
[C19: from Greek meristos divided, from merizein to divide, from meris portion]
meristematic adj

mer•i•stem

(ˈmɛr əˌstɛm)

n.
embryonic tissue in plants; undifferentiated, growing, actively dividing cells.
[1870–75; < Greek merist(ós) divided, distributed + -em < Greek -ēma]
mer`i•ste•mat′ic, adj.

mer·i·stem

(mĕr′ĭ-stĕm′)
Plant tissue whose cells actively divide to produce new tissues that cause the plant to grow. The cells of the meristem are not specialized but can become specialized to form the tissues of roots, leaves, and other plant parts. The growing tips of roots and stems and the tissue layer known as cambium are part of a plant's meristem.

meristem

Plant tissue consisting of rapidly dividing cells.

7) We observed a considerable decrease in meristematic cell number in the triple mutant to a level similar to that of the tpst-1 mutant, accompanied by insensitivity to RGF, and named these receptor proteins RGFR1, RGFR2, and RGFR3.
According to Smet e Beeckman (2011), the adventitious root initiations involves the meristematic cell niche formations (initial cells and/or target cells) which are dependent on external and internal factors.
Doryopteris triphylla follows a pattern of development that is easily ascribed to the Adiantum type (Nayar & Kaur 1969), in which a more or less obconical meristematic cell is established in early stages of development, the evolution of which lead to the acquisition of an apical multicellular meristem.
The following parameters were analyzed in each specimen: a) the frequency of the of micronuclei in erythrocytes were detected under a Binocular microscope (OLYMPUS) using a 10X100 oil-immersion lens within 2000 meristematic cell.
Once the filament was differentiated, a two-dimensional thallus developed in two ways: 1) from the apical cell of the filament which divided crosswise forming two unequal cells whose function is to form a meristematic cell that will initiate the development of the plate, or 2) through the lengthwise division of the intercalary cells of the filament that gave place to the plate phase and, later, to the establishment of a pluricellular meristem (Figs.
Ultrapetala and other genes use these pathways to control the fate of cells, determining, for example, whether a meristematic cell will differentiate into a sepal or petal.
3,5), the tunica consists of one or more meristematic cell layers over the surface, in each of which cell division is only anticlinal, perpendicular to the outer surface.
Cytotoxic and/or genotoxic effect of AgNPs and the ability to induce various chromosomal aberrations in mammalian cells, bacteria and root meristematic cells of different plants were reported in numerous studies (Patra et al.
Based on the discussed context, the goal of this study was to evaluate cytotoxicity, genotoxicity and mutagenicity of processed liquid preparations ready for consumption, Orange and Grape flavors, of five relevant food companies in the Brazilian market, through the meristematic cells of A.
Deficiency of B affects vegetative as well as reproductive growth in plants thus causing cell expansion inhibition, death of meristematic cells and reduction in plant fertility (Marchner, 1995).
Table 1 presents the number of cells in interphase and at different stages of cell division, and the values of mitotic index obtained from meristematic cells of A cepa roots treated with water and food flavorings of Passion Fruit and Vanilla.
