Why is "de" necessary in, "Les plantes produisent de l'oxygène?"

Bonjour Susan !
In this sentence, it's because we're considering that oxygen is not a countable thing (i.e. "Plants produce some oxygen."), therefore you need to use the partitive article, i.e. de l' .
However, I agree that in this case, plants produce oxygen in general, therefore it would be more accurate to say : "Les plantes produisent l'oxygène.".
Thanks to you, I edited the example.
Merci et à bientôt !
