Is it? Or does that depend upon your ontology/definition? (02)
If you see an acorn, do you see a tree? If you see an acorn with
a live shoot and root having emerged do you see a tree? If you
see an oakling do you see a tree? (03)
If you see two different trees, do you see two different plants? (04)
A grove of aspen is a single organism. A single root system
underlies the grove. Individual "trees" are different trunks
or "shoots" from the connected root system. Some may call
these "clonal colonies" instead of "organisms", but that makes
it an arbitrary exercise to specify a boundary between organisms. (05)
I note that fruit and nut trees are commonly grafted, with different
parts of the tree coming from different organisms -- even different
species. This also makes a definition of "tree" more difficult. (06)
