In the plant cell model that Mario presented, a horse chestnut took the place of the nucleus, a handful of plasticine was the cytoplasm, the organelles were represented by lentils and other beans, small bits of green pipe cleaner served as chloroplasts, and the plastic bottle that held everything was the cell membrane, surrounded by a thick papier-mâché coat for the cell wall.
En el modelo de célula vegetal que presentó Mario, una castaña de Indias hacía las veces de núcleo, un puñado de plastilina era el citoplasma, los orgánulos estaban representados por lentejas y otras legumbres, trocitos verdes de limpiapipas figuraban como cloroplastos y el plástico del envase que contenía todo era la membrana celular al tiempo que una gruesa capa de papel maché servía de pared celular.
