Apical Cell Theory: This theory was proposed by Nageli who drew the attention to the occurrence of a single apical cell or apical initial that composes the root meristem. A single apical cell is present only in vascular cryptogams, e.g. Equisetum, Adiantum and Polypodium etc. Intersected functional zone of transcriptional regulators patterns stemness within stem cell niche of root apical meristem Meizhi Xu College of Life Sciences, FAFU‐UCR Joint Center and Fujian Provincial Key Laboratory of Haixia Applied Plant Systems Biology, Fujian Agriculture and Forestry University, Fuzhou, 350002 China The three primary meristems first appear in the embryo proper, with the protoderm on the outside, the procambium in the center, and the ground meristem in between them. Figure \(\PageIndex{1}\): A longitudinal section of the shoot apex of Coleus includes the shoot apical meristem and the The apical meristem is typically divided into two categories, the shoot apical meristem, and the root apical meristem. The shoot apical meristem of the plant grows rapidly and eventually produces not only the stem, shoots, and leaves of the plant but also all parts of the flowers such as the ovaries, petals, stamens, and sepals. Previous work showed that the microtubule-associated protein CLASP sustains root apical meristem size by influencing microtubule organization and by modulating the brassinosteroid signaling pathway.

No apical meristem (NAM) protein Provide feedback.

The apical meristem is the growing tip of a plant, and is undifferentiated meristematic tissue located at the growing shoot tips and buds of plant roots. The main function of the apical meristem is to start the growth of new cells at the shoot and root tips of plants.

spetsmeristem. (botany, of a meristem) Situated at the growing tip of the plant or its roots, in comparison with intercalary growth situated between zones of permanent tissue.

This longitudinal section through a shoot apex in Coleus shows the tip of a stem. Between the young leaf primordia is the apical meristem. The meristem which occurs between mature tissues is known as intercalary meristem. They occur in grasses and regenerate parts removed by the grazing herbivores.

Apical Meristem Structure. The apical meristem is found in the roots just below the root cap. The apical meristem is a tightly packed cluster of undifferentiated cells. Many of the plant's different cell structures are derived from these cells. Undifferentiated apical meristem cells divide repeatedly, eventually transforming into specialized cells. Abstract. The shoot apical meristem generates stem, leaves, and lateral shoot meristems during the entire shoot ontogeny.

Ferns (monilophytes) and some lycophytes, including Selaginella moellendorffii, have apical meristems that are unusual compared to the apical meristems of angiosperms.Fern and Selaginella apical meristems have a single distinct apical, pie‐shaped cell whereas the angiosperm meristem is multicellular with distinct zones and layers and no apical cell (Fig. 1).

They help in the growth of the root system as well as the shoot system. The various  The root apical meristem (RAM) is the simpler of the two apical meristems.

Apical meristems of most plants have the function to reiterate the modules of leaves, which are optimized to capture light, and thus are the major places for photosynthesis.
