Para realizar la fotosíntesis las plantas necesitan varios elementos que se encuentran en el medio ambiente.

Energía luminosa: impacta sobre las hojas y es absorbida por el pigmento fotosensible de la planta, la clorofila.
Agua: La fotosíntesis requiere un suministro constante de agua. Ésta llega a las hojas a través de las raíces y tallos.
Clorofila: Pigmento de color verde contenido en el cloroplasto. Se encarga de la absorción de la luz, para llevar a cabo la fotosíntesis.
Dióxido de carbono: Es absorbido por unos minúsculos poros, llamados estomas, en la parte inferior de la hoja.
Oxígeno: subproducto de la fotosíntesis. Sale de las hojas hacia el exterior a través de lasestomas.
