| dc.description | The present information allowed us to know about the principles of basipetal mobility of nutrients by the conductive tissue of plants.The basipetal movement occurs within the stem, right in the phloem of the plants where nutritive solutions move, including biomolecules such as: glucose, carbohydrates, among others in a bidirectional way (from top to bottom and vice versa), that have been produced in the photosynthetic process and that serve for its growth, development and production. The primary phloem is the first type of phloem that appears in In developing organs, it appears first as a protofloem and later as a metaphloem. The protofloem is formed from the procambium, which is the meristematic tissue that appears early in the embryo, from which the primary conductive tissues originate. The conductive tissues of plants are responsible for guiding the long-distance passage of nutrients through the different structures of the plant organism. Plants that have conductive tissues are called vascular plants. There are two classes of conductive tissues: xylem and phloem. The xylem is made up of the tracheal elements (the tracheids and tracheas) and is responsible for the transport of water and minerals. The phloem, the second type of conductive tissue, is formed mainly by sieve elements and is responsible for conducting the products of photosynthesis, redistributing water and other organic materials. We can find the existence of a conduit made up of living cells; the high concentration of sugars in the transport solution of up to 33%; and the positive pressure, higher than atmospheric, at which this content is found; here the basipetal sense of transport, opposite to the transpiratory current, at the base of the stem | es_ES |

| dc.description.abstract | La presente información permitió conocer sobre los principios de la movilidad basipetal de nutrientes por el tejido conductivo de las plantas. El movimiento basipetal se da dentro del tallo, justo en el floema de las plantas donde se mueven las soluciones nutritivas orgánicas, entre ellas las biomoléculas como: glucosa, carbohidratos, y otras de forma bidireccional (de arriba hacia abajo y viceversa), que se han producido en el proceso fotosintético y que sirven para su crecimiento, desarrollo y producción. El floema primario es el primer tipo de floema que aparece en los órganos en desarrollo, surge primero como protofloema y más tarde como metafloema. El protofloema se forma a partir del procámbium que es el tejido meristemàtico que aparece tempranamente en el embrión, a partir del cual se originan los tejidos conductores primarios. Los tejidos conductores de las plantas son los encargados de guiar el paso de nutrientes a larga distancia por las diferentes estructuras del organismo vegetal. Las plantas que presentan tejidos conductores son llamadas plantas vasculares. Existen dos clases de tejidos conductores: el xilema y el floema. El xilema está compuesto por los elementos traqueales (las traqueidas y las tráqueas) y se encarga del transporte de agua y minerales. El floema, el segundo tipo de tejido conductor, está formado principalmente por los elementos cribosos y se encarga de la conducción de los productos de la fotosíntesis, redistribuye agua y otros materiales orgánicos. Podemos encontrar la existencia de un conducto constituido por células vivas; la elevada concentración de azúcares en la solución de transporte de hasta un 33%; y la presión positiva, superior a la atmosférica, a la que se encuentra ese contenido; aquí el sentido basípeto del transporte, opuesto a la corriente transpiratoria, en la base del tallo. | es_ES |
