I didn't think it'd be this way before, but at this point I wouldn't be surprised if Kishi did that.

it is my theory that the fruit was the shinju's life force or heart when she ate the fruit the shinju died. we know the shinju is not sentient it was just a tree that had a strong life force. it was simply akin to a powerful organism. she consumed the fruit and gained the same powerful life force. she then molded her physical and spiritual energies together creating chakra her children were born with it and she wanted that chakra back because she was weaker with out the chakra they gained so she created a massive form(the juubi) to take back the power
