Because his flesh = his DNA, and clearly his ability to mix water and earth to create wood lies within it. Kekkei genkai is like its name suggest - bloodline, meaning it is passed by blood = by DNA. Look at Haku - he could create ice because his mother could and he inherited it from her. Naruto survived Kurama's extraction because he inherited stronger vitality from Kushina (though it wasn't KKG, just the trait), etc.

@Elveonora - true. Bijuus may have been "just chakra" before Hagoromo created them, but then they became living beings, with their feelings, intelligence etc.
