Do plants die of old age though? Now that question has been put in my head, I need to know.

Be back in a bit, going down a rabbit hole.

Given the right conditions, some plants can live indefinitely. Others die shortly after seeding.

There's a bristlecone pine tree in the White Mountains of California that is nearly 5000 years old.

Depends how you look at it. If you keep raising off-shoots from cuttings, you are essentially producing extensions of the very same plant and you can do that indefinitely. Think about it like cloning: an individual plant will eventually die, but it's clone will survive and can still propagate.

Plants are not biologically immortal like some lobsters for example.

[–] 9point6@lemmy.world 21 points 10 months ago (1 children)

Tell me more about these lobsters

Chromosomes are essentially packages of DNA and each end of a chromosome is extended by a protein called telomere, essentially sequences of "junk data" that protect the actual data (the DNA) from degradation or randomly fusing with other chromosomes. When cells split to renew, these telomeres are not fully copied to the new cell and thus shorten with each split. When they get too short, cells cannot split anymore, so there is a natural end to the renewal process (the so-called Hayflick limit).

Lobsters possess an enzyme called telomerase which can repair telomeres and thus their cells can, in theory, divide indefinitely. They will still die naturally tho due to diseases or growing too large to sustain their body size and die of malnutrition, but they don't age the way we do.

That was super interesting, thanks for the response

Vine plants are especially weird.

Should we send someone after him?

Dammit, this is why you always secure your lifeline before entering the Rabbit Hole

[–] Late2TheParty@lemmy.world 12 points 10 months ago

You gotta tell us some fun things you learned!

[–] frank@sopuli.xyz 11 points 10 months ago

Subscribe to plant facts

wait until you get to the part about the Ginkgo tree

[–] icerunner_origin@startrek.website 2 points 10 months ago

It is the horseshoe crab of trees

I love talking with kids in that phase. The raw curiosity and interest in the mundane is so refreshing.

Sometimes I feel like many adults hate to learn new stuff and even get offended by the idea. It's heartbreaking seeing those interact with inquisitive children, when they answer honest curiosity with indifference or worse anger.

[–] Amanduh@lemm.ee 22 points 10 months ago (1 children)

Kids can be annoying sometimes, especially if you let them live in your house

[–] OhVenus_Baby@lemmy.ml 3 points 10 months ago

This is why I choose not to have kids. Actually because current state of affairs and their like a boat anchor to freedom.

[–] Agent641@lemmy.world 10 points 10 months ago

I like it when they are circling a question where the answer is "Nobody knows yet.' And when they get there I can hit 'em with the finishing move, "Maybe you'll be the first person to find out!"

Hooks them every time.

[–] pyre@lemmy.world 8 points 10 months ago

my kid has been teaching me shit constantly. either by having facts about animals i didn't know before (which i have checked and verified) or asking me questions where my answer was "i don't know, let's look it up".

i was always a curious person myself and constantly asked questions as a kid as well, but as you grow up you sometimes take things for granted and forget to ask why something is the way it is or how it came to be so. now my kid looks at the world with fresh eyes and asks questions i haven't asked, so we can both learn. it's awesome.

reminds me of the monologue that woman delivers in Love Death and Robots episode Pop Squad.

There's a science article that investigated why the Brits discuss the weather? I'm now mildly curious to know their methodology and conclusions...

[–] SpaceNoodle@lemmy.world 15 points 10 months ago (1 children)

I like that it's a foregone conclusion, not just weather or not they do.

[–] Viking_Hippie@lemmy.world 6 points 10 months ago

It is? I hadn't the foggiest!

[–] thisbenzingring@lemmy.sdf.org 9 points 10 months ago (2 children)

they still think digital watches are a pretty neat idea

[–] flerp@lemm.ee 5 points 10 months ago

I still think mechanical watches are a pretty neat idea. I also never forget my towel so there's some hope for me yet.

[–] toynbee@lemmy.world 3 points 10 months ago

I like this reference.

It's like being subscribed to a toddler in the "why" phase.

[–] aramis87@fedia.io 18 points 10 months ago

If BBC Science Magazine was texting me at 1.29am to ask "Why do the British talk about the weather so much?", BBC Science Magazine and I would be having words - especially if they texted me six hours later to ask about plants!

Yeah, he thought it was a different kind of BBC notifications. ಠ⁠◡⁠ಠ
