I put this ivy plant in a water bottle with some water, and no air can get in or out, and its growing???

Question

THe ivy that is in the water bottle has like 2inches of water in it, and no air can get in or out of it. And the plant started a new root???? how can this be? It has no carbon dioxide to live off of.. only pure oxogen im guessing? It has sunlight and water, and thats it!!

how can this be? its been like a month and it is still living!

Answer 1

Plants don't breathe CO2 all the time.  At night, when there is no sunlight for photosynthesis, they switch over and breathe oxygen, just like we do.  So, my best guess is there's some sort of equilibrium the plant has created that is helping keep it alive.  Obviously the balance of gasses in the bottle won't last forever and the plant will die off.  

A better question is, why are you trying to kill the plant? Is it for a science experiment or something, or were you just curious? :3 Poor ivy plant! I shall call him Bob. Bob the survivor.

Answer 2

ivy is pretty hearty and invasive, it might be the strength of the plant, or possibly the water bottle isn't as sealed as you think it is, don't underestimate the power of the plant! lol

Answer 3

maybe it doesn't required the others
