OK, I know I'm going to hear moans and groans and the truth is, I threw them away.
I'm pretty regemented in my seed growing and only use this sprouting technique to check germination. As dice has said, yes you can transplant these sprouts and they will grow into normal plants.
I just thought of something, I have a seed sprouter at home (for sprouting the type you eat) and it has four chambers that stack on one another with a lid for the top. I'll have to try it the next time I do a test and won't have to mess with the ziplocks or filters. Ami
