Perennially Young?

Plants' capacity to renew spent parts thwarts aging, but our green cohabitants might not elude the process completely

Abstract: Compared with animals, plants seem to defy age. Many trees thrive for thousands of years--or maybe more. Some scientists attribute plants' knack for staying fresh to their segmented body plan and ability to renew spent parts. Yet emerging evidence suggests that plants can't elude feebleness entirely. They apparently suffer from the same wear and tear that animals do, an observation that calls their ultimate resilience into question.
