noob question about seeds

Hello.

I have a seeded plant but I just harvested it. I was wondering if the seeds will mature or if cutting the plant makes them stop from doing so. I mean, do they need to be attached to the plant (plus the plant being alive) or can I collect them from the buds and seeds will mature on their own?

Hope it's understandable

Seeds mature on the living plant.

Ok thanks. Won't be able to use them I guess

do they look developed?

Not really. It looks like a greenish white color and some are a bit brown. I've put like 10 of them in a glass of water. I don't think the seeds will sprout but ill try. I heard some people germinate white seeds successfully.

Prob means you harvested early. If the plant was ready to come down the seeds would be further along.
But yes some people I've heard has sprouted them.
