A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

Plants, through photosynthesis, take in carbon dioxide and release oxygen as a byproduct

We breathe their BO not their farts.

It's exhalations really. Their BO would result mostly from bacteria that live on their surface. You exhale your metabolic byproduct of CO2, they exhale their O2. Just, instead of one centralized set of "lungs", their respiratory system is decentralized through the structure, kinda like a lobsters "brain" is. Kinda.

Naw, the farts are actually the best comparison.

Plants "breathe" normally too, taking in oxygen, and producing CO2. Separately, they also take on CO2 and sunlight, and produce "food" and expel oxygen.

Since it's a by-product of their "eating"... It really is a fart, isn't it?

The main thing for me is that the contents of flatulence and BO were not made by the animal themselves. They were made by symbiotic bacteria.

Regarding plants taking in O2 and expelling CO2, to my knowledge this only happens at night, and the plant is not actually using the O2. It's just concentrations naturally equalizing while it waits for the sun to come back. Do some plants actually have a use for O2? That's out of my wheelhouse.

Anyways, I can see the flatulence argument, since both are a result of a "feeding" behavior, but there's not a lot else in common.

Plants do indeed use O2. They use if for the same reason we do, the have mitochondria that use O2 during respiration.

During the day plants typically produce more O2 than they consume, but at night they need it from elsewhere.

I guess, yea, they're making sugar, but they're still going to need to metabolize it. Why do I have the impression I probably knew this at one point in time...?

Oh sweet. The new "airplane on a treadmill" problem just dropped. 🍿
