Intensidade Luminosa

     No ponto A a planta apenas respira, pois a fotossíntese é nula. No ponto B a planta se encontra no ponto de compensação fótico, onde a intensidade da fotossíntese e da respiração é igual. No ponto C a planta atingiu o ponto de saturação luminoso, ou seja, a partir desse ponto o aumento da intensidade luminosa não produz aumento na intensidade da fotossíntese.

Sabia que a fotossíntese alem de ser um processo realizado por plantas, tambem é realizado por algas, algumas bactérias e cianobactérias.

Adriana said...

Entao quer dizer que a fotossintese so ocorre quando tem luz solar? Ele funciona se colocar luz de lampada?

Paola said...

É claro que nao Dri... A luz solar e o CO2 sao essenciais para que o processo aconteca.
