Green tap root

Just the cotyledons showing. Image 2 has some gross hair in there. Clean up your germination space, Cheers!

if a root is exposed to light, it will start to differentiate into a stem and no longer a root... this may be something else, but this can and will happen as described, too. Along with extra opportunities for contamination, paper towel method often exposes roots to light. roots don't like light.. they will morph into stem and lose the ability to absorb water over time. (doesn't happen overnight, which makes me think twice about what i see in pictures here) so, if you weren't keeping them dark before, do that in future.

Just a mutation. It'll be fine. Good luck.

Very strange, never seen anything like it, but plant it asap and everything should be alright.

Такое бывает. Ничего странного и ничего страшного. Для проросшего семени это в рамках нормального.
