Phloem Apoplast Route Sucrose Describe Loading Travels Cell

The apoplast route for phloem loading involves sucrose traveling through cell walls and intercellular spaces to companion cells and sieve elements by diffusion, maintained by sucrose removal into phloem vessels.

La ruta apoplástica para la carga del floema implica que la sacarosa viaje a través de las paredes celulares y los espacios intercelulares hasta las células acompañantes y los elementos cribosos por difusión, mantenida por la eliminación de sacarosa en los vasos del floema.
