At what point is a plant 'alive', or 'dead'?

[SickThings]

At what point is a plant 'alive', or 'dead'? They do not have a pulse, or breathe, so how can we tell when they are dead? Are seeds, or vegetables 'alive', because they are capable of growing?

From biology lessons I remember that something is defined as living if the GRIMREN conditions are satisfied (any of them?)

Growth, Respiration, Irritability, Movement, Reproduction, Excretion, Nutrition.

[WaldoMcFroog]

Not any of them, *all* of them.

Sickthings, you're wrong to say plants don't breathe; they don't breathe like we do, but they certainly do respire.

[SickThings]

I meant that they do not breathe in a physical form that would enable us to determine if they are alive or dead.
