IMPORTANCIA MUNDIAL
Mas de 2500 millones de toneladas de CO2 son trasformadas en alimento anualmenteAlternativa mayor para disminuir efecto del calentamiento globalProvee de Oxígeno a los demás seres vivosEl proceso que mas se investiga en el mundo

Principios aplicados
Fluorescencia: captación de la energía lumínica. Excitación de los pigmentos activos
Efecto Emerson: - demuestra la actividad de los pigmentos- Participación de los mismos en fase lumínica

Plantas C3
En general son las plantas que cumplen la fase lumínica y la fase oscura como lo explicado anteriormente.La dotación de cloroplastos principalmente activos son los llamados cloroplastos del mesófiloCon un solo captador de CO2: la ribulosa 1,5 difosfatoPlantas de clima frio: hortalizas, trigo, papa cebada; algunas de clima cálido tabaco, arroz • Gastan mas agua para producir un gramo de
materia orgánica seca.• Presentan alta tasa de fotorespiración• Representan entre un 90 a 93% de todas las
plantas
