What's a body? It doesn't have to be anything more than ones and zeros.
in order for a tree to reproduce, it must sprout first, and have a life in which it produces a flower, which gets pollinated, generally speaking. The important point is that from that flower which is pollinated, eventually, a fruit is formed. When the fruit is formed and detaches, that detached fruit is the state of death. even if the tree dies, it can revive through what it stored within its fruit.
