Durante el 2° período académico, los estudiantes de 7° de un colegio de Armenia estudiaron los diferentes tejidos vegetales e hicieron un experimento con una planta de fríjol. Para el experimento, regaron con agua únicamente las hojas superiores de la planta, impidiendo por completo la caída de agua a la tierra en la maceta. Al cabo de 1 mes arrancaron la planta de raíz para estudiar esta zona y se dieron cuenta de que, si bien la tierra estuvo completamente seca durante todo el mes, las raíces se habían mantenido bien hidratadas. ¿Qué tejido podría explicar los resultados observados por los estudiantes de 7°?
