meristem

meristematic tissue

a region of a plant in which active cell division (MITOSIS) occurs, the cells of the meristem not being differentiated into a specialist form. Meristematic tissues occur at the root and shoot tips (see APICAL MERISTEM giving growth in length, while increase in girth of the plant is produced by the CAMBIUM of VASCULAR BUNDLES and the INTERFASCICULAR CAMBIUM. Note that such specialist dividing zones are not found in animals, where cell division occurs in most tissues.

In the developing fruits of Fabaceae (Leguminosae) and Rutaceae usually occurs the installation of ventral or adaxial meristem which originates from the ovary epidermis and/or mesophyll (ROTH, 1977; SOUZA, 2006).

This midge attacks the terminal meristem of a developing shoot, producing an apical bunch or rosette gall that provides protection for the developing midges and a habitat for a community of other insects.

Because we clipped aspens on the main stem, a loss of apical meristem dominance may help explain the compensatory response we observed.

As explained in Barthelemy and Caraglio (2007), organogenesis results from the functioning of undifferentiated cells constituting the apical meristem and located at the tip of axes.

To understand why Fibonacci numbers predominate in spiral plants, Gole and Atela started with the theories of 19th-century botanist Wilhelm Hofmeister, who observed that a plant's leaves emerge at the least-crowded spot around a circular meristem, or growing tip.
