  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. An individual plant will eventually die tho as they are not biologically immortal like some lobsters fot example.

      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 to large to sustain their body size and die of malnutrition, but they don’t age the way we do.
