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 1 month ago

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 1 month ago

You gotta tell us some fun things you learned!

wait until you get to the part about the Ginkgo tree

[-] icerunner_origin@startrek.website 2 points 1 month 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 1 month ago

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

[-] OhVenus_Baby@lemmy.ml 3 points 1 month 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 1 month 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 1 month 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.

[-] ByteJunk@lemmy.world 38 points 1 month ago

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 1 month ago

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

[-] Viking_Hippie@lemmy.world 6 points 1 month ago

It is? I hadn't the foggiest!

[-] thisbenzingring@lemmy.sdf.org 9 points 1 month ago

they still think digital watches are a pretty neat idea

[-] flerp@lemm.ee 5 points 1 month 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 1 month ago

I like this reference.

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

[-] umbrella@lemmy.ml 21 points 1 month ago* (last edited 1 month ago)

because you shook your neurons..

there wouldnt be tides

they lose a bit of energy every time they bounce

some do some dont

because their weather is awful go to sleep right now timmy im losing my patience.

[-] AngryCommieKender@lemmy.world 4 points 1 month ago

That second one may do a lot more than just no tides. The planet may not be habitable without the moon. I don't remember the specific details right now, but those tides have something to do with levelling out our weather patterns.

[-] praise_idleness@sh.itjust.works 4 points 1 month ago

Literally all of the questions can be answered by a smart little 12 year old.

[-] XTL@sopuli.xyz 1 points 1 month ago

But it's the target audience (people who might subscribe to BBC notifications) as smart as a little 12 year old?

[-] aramis87@fedia.io 18 points 1 month 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!

[-] BenReilly97@lemmy.world 7 points 1 month ago
[-] AFC1886VCC@reddthat.com 5 points 1 month ago

No. Not this time. It's fiction. We made it up. This one was invented by a writer. We got you. It never happened.

[-] BenReilly97@lemmy.world 4 points 1 month ago

You're right. A similar event took place. Yes, it was. You were correct. It's fact. This one took place. Right again. A similar story happened to a young man in the Pacific northwest about twenty years ago. Yes.

[-] Slovene@feddit.nl 6 points 1 month ago

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