A Cor Verde das Plantas
Aristóteles tinha observado e descrito que as plantas necessitavam de luz solar para adquirir a sua cor verde. Só em 1771, o estudo do processo fotossintético começou a ser observado por Joseph Priestley. Este químico inglês, confinando uma planta numa redoma de cristal comprovou a produção de uma substância que permitia a combustão e que, em certos casos, avivava a chama de um carvão em brasa. Posteriormente, concluiu-se que a substância observada era o gás oxigênio.
