O QUE SIGNIFICA PROCAMBIUM EM INGLÊS
Meristem
Um meristema é o tecido na maioria das plantas que contém células indiferenciadas, encontradas em zonas da planta onde o crescimento pode ocorrer. As células meristemáticas dão origem a vários órgãos da planta e mantêm a planta crescendo. O meristema apical do tiro dá origem a órgãos como folhas e flores, enquanto o meristema apical da raiz fornece as células meristemáticas para o futuro crescimento da raiz. As células SAM e RAM se dividem rapidamente e são consideradas indeterminadas, na medida em que não possuem nenhum status final definido. Nesse sentido, as células meristemáticas são freqüentemente comparadas às células-tronco em animais, que têm um comportamento e uma função análogos. O termo meristema foi usado pela primeira vez em 1858 por Karl Wilhelm von Nägeli em seu livro Beiträge zur Wissenschaftlichen Botanik. É derivado da palavra grega merizein, que significa dividir, em reconhecimento de sua função inerente. Em geral, células de plantas diferenciadas não podem dividir ou produzir células de um tipo diferente.
definição de procambium no dicionário inglês
A definição de procambium no dicionário é tecido vegetal indiferenciado, logo atrás da ponta crescente em hastes e raízes, que se desenvolve em tecidos condutores.

Introductory Botany: Plants, People, and the Environment, ...
Three primary meristems (immature tissues) are found in the area of cell
elongation: protoderm, procambium, and ground meristem. The protoderm is
young, undifferentiated tissue of a root or stem that eventually develops into
epidermis.

INITIATION The vascular cambium normally differentiates from the procambium.
although it can also arise within a callus. The procambium is a partially

Current Trends in the Embryology of Angiosperms
Thus, after the octant stage the embryo becomes globular. Internal cells of
proembryo will then differentiate into the procambium and ground meristem. The
hypophysis, a special cell, is differentiated between the embryo proper and
suspensor.

In addition, cell divisions at right angles to the long axis of the stem are infrequent
in the procambium. In sectional view, therefore, the procambium appears as a

The development of collenchyma in the Umbelliferae clearly illustrates the lack of

development. In mature petioles of celery, collenchyma strands appear near the ...
