    Todas las raíces de las plantas comienzan en el crecimiento primario, que es un alargamiento de los órganos de las plantas. El crecimiento primario involucra el meristemo apical de la raíz, meristemos primarios y tejidos primarios.

    El pasto de trigo recién germinado retirado de su contenedor
    Figura\(\PageIndex{1}\): Estas semillas de pasto de trigo han brotado recientemente, produciendo crecimiento fresco de raíces y brotes. Este sería un excelente lugar para buscar raíces en crecimiento primario. Tenga en cuenta que, a pesar de que es un desastre enredado, las raíces individuales no se ramifican mucho. En cambio, están creciendo como hilos largos y delgados. En la punta de cada uno de estos hilos, encontrarías un meristemo apical radicular. Foto de Maria Morrow, CC BY-NC.

    Video\(\PageIndex{1}\): Este video de Ben Montgomery proporciona un recorrido por las estructuras internas y la organización de las raíces de las plantas, incluida la formación de raíces laterales. Se obtiene de YouTube.
