Lettuce pip roots are fuzzy and white....?? proper germination? I know I asked a similar question yesterday. But I'm wondering if...

I know I asked a similar question yesterday. But I'm wondering if the nut coat really needs to split open out in writ for it to count as germination? Does the seedling HAVE to be green in writ for to be alive and growing? Also, some roots going out don't have white fuzz and some do. The seed coats are all wheaty colored and didn't come across to grow in size at adjectives. What's up with that?

Thanks
