Los Briófitos (MUSGOS) ● No tienen tejidos, ni órganos especializados ● Pequeño porte ● Necesitan bastante humedad y sombra ● Sin semillas ni flores ● Reproducción alternante: ● Fase asexual o esporofito más pequeño. ● Fase sexual o gametofito más grande. Hay gametofito masculino y femenino.

  5. 5. Los Pteridófitos (HELECHOS) ● Mayor tamaño que los briófitos ● Mejor adaptados al medio terrestre, pero todavía necesitan humedad para la reproducción ● Tienen tejidos y órganos especializados, es decir, tienen raiz, tallo y hojas ● Tampoco tienen flores ni semillas ● Reproducción alternante: El esporofito es bastante más grande que el gametofito. En el gametofito se producen los gametos masculinos y femeninos
