How does air get inside e.g. a bell pepper? Why aren't they a vacuum?
There's seeds inside. If there's seeds - they were pollinated at flower stage. Pollen somehow got there, so there were air. Then the bell has closed.
>>17050899Plant cells produce gasses as a byproduct of their metabolism.I'm confused on why you're confused about this.
>>17050948well I'm not litterally in profound disbelief but I'm interested nonethelessI would have guessed air just very slowly seeps in from outside so this:>Plant cells produce gasses as a byproduct of their metabolism.is interesting. So the composition could be quite different from ambient air? More CO2 and less oxygen?

>>17050980intredasting thanks, wouldn't have thunk it desu
>>17050948>Plant cells produce gasses as a byproduct of their metabolismThen all plants should be foamy, but they are not. That means that gases aren't trapped in a tissue. Then why they would be trapped in a paper or pumpkin?
>>17051092Obviously it depends on other things too.
I just submerged a pepper and squeezed it a bit, air bubbles came out of the cut stem so its not fully airtight. I know that CO2 and O2 can diffuse across plant cell walls too.
>>17050980Makes sense. Plants aren’t impermeable. They have pores. They need air for respiration
Air even escapes through the rubber of a balloon. It doesn't sound loke a surprise that it would pass through bell pepper walls as well
