Full.Cream:Is part of living thing a living thing. We are living thing, is our nail living thing. We are living thing, but when we die what are we. So must we say that living human is a living thing? It gets more and more cumbersome as it goes.1stly, if they say 'apple', it's almost always a standalone apple. It wld be very cheeky to insist that the apple is still on the tree.
Eg, if there's a science qn on which of these (chick, puppy, tadpole) hatch from egg, we don't try to be funny and ask what if the egg is not fertilized, ya?
From a science question, it becomes a philosophical discourse.
By definition, living thing can grow, respire, reproduce.
Asking the question is seed a living thing, is like asking if an embryo is a baby. Of course it is a living thing, it respire and grow eventually reproduce.
Conclusion, the question is not well thought of, the writer of the question did not pay too much attention in crafting it and therefore do not require too much of our attention as well.
