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.

Hypocotyls were carefully excised (1-3 mminlong) from the seedlings without meristematic axillary buds.
The reduction in the growth of 'BRS Rubi' cotton, observed through the decrease in SD and PH, can be attributed to the reduction in the osmotic potential of the soil solution, to the restriction to water flow and to the ionic effect caused by the accumulation of ions in the plant tissues, which directly affects the meristematic activity and cell expansion, consequently causing a decrease in plant growth (Munns & Tester, 2008).
