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
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    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 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...?
