Para empezar pensando…..

• ¿Cuál es la unidad funcional y estructural de todos los seres vivos?

• ¿Qué dos tipos principales de células existen? ¿Podrías dibujarlos señalando sus diferencias?

• ¿Qué son las biomoléculas? ¿Recuerdas cuáles son?• ¿Qué tres funciones realizan todos los seres vivos?• ¿Qué diferencia hay entre la nutrición autótrofa y la

heterótrofa? ¿Qué seres vivos presentan cada una?

ORGANS

Formed when several tissues join together, their functions complement each other, and produce more complex functions.
