Subject: Aldrovanda bubbles

Hello!

I know this is stupid, but I'm just curious...
Has anyone noticed that Aldrovanda expels continuously the oxygen it
produces in photosynthesis through the old (dead) part of the stem? When I
look at it, I see lots of bubbles being expelled through there (only in the
day). Why doesn't the oxygen just diffuse into the water?

Ok, it is a stupid question... Forgive me.

Good growing!
Miguel
