so if given the right amount of nutrients etc for ever are trees immortal?

Answer 1

Actually trees that are in harsh climates where they don't get unlimited sun and water seem to last the longest.

Answer 2

Ten thousand feet up in California's White Mountains lives the oldest living thing on Earth. It is a bristlecone pine that was around when the Egyptian Pyramids were built. Ironically, after weathering all the droughts, high winds, and lightning strikes that must have struck over the millennia, the nearly 9,000-year-old Methuselah Tree now faces threats from the one force of nature that seemingly can do it harm: people.

Answer 3

Still nothing lives forever - not trees, not the earth and not the universe.

Answer 4

I don't believe so - We as humans have all the capacity to keep on making new cells and live forever, but there is some code in our cells that tells our body to stop renewing itself at some point and thats why we deterierate as we get older. So if all animals die after a set time, i would expct tree would too, however their maximum life span may be alot longer than ours.
