I always believed that baby Groot is the original Groot but reborn because plants can be cloned quite easily.
The simplest way to clone a plant involves taking a cutting. A branch from the parent plant is cut off, its lower leaves are removed, and the stem is planted in damp compost.
I always imagined the Guardians cloned Groot using simple plant cloning and then let him grow. One of the reasons is that they didn't seem to think much about Groot's death after Baby Groot sprouted and some basic biology skills.
I always believed that the original Groot was killed but the baby Groot was a genetic clone of his older version however my friend told me that Baby Groot is actually Groot's son.
My question is: Is the original Groot dead and Baby Groot is his offspring of is baby Groot or his genetic clone?
Even if he is not a genetic clone I will still choose to believe he is one because its too sad to know the original Groot died!
PS: My question is not is Groot dead because he has been genetically cloned because that's opinionated and it's kind of up for discussion.
