xxx: I was faced with this approach at the moment, there was a question, which creatures of their parts can reach a mass of several hundred tons?
The answer was about mushrooms, their part - the mushroom, in fact, it is as if it were not a part, it is the mushroom itself, the fruit bodies - it is so, the spore reproduction, growing as necessary, mushrooms - like these are living beings.
I answered, and pulled the command, that these are trees, their trunk can reach several hundred tons, and it is precisely part of a living being.
We were answered that the trunks are not alive, and like plants are not alive, so mushrooms are alive, read the children’s encyclopedia.
No, I understand the fundamental error, of course, this is such a vulgar philosophical aspect, as it is now considered and why, trees are alive or not alive, why are mushrooms alive?

YYY: Oh, I don’t even know what to say...give an example of a roosie or a venus flies...I don’t know how good an example is, of course. I am a dilettant. But the question is, are these plants alive? Or not alive?=) I think that "trees are not alive" sounds silly.

zzz: It would be right to send the organizers in the ass.
