Difference Between B.Sc And BSc.Ed?

I've been asking this question around& I haven't get a suitable response, so I brought it here...guys pls what's the difference between Bsc&Bsc.ed, does someone with a Bsc.ed degree has the same chance with a Bsc holder? And I heard all Bsc.ed holders will end up teaching is this true? Cos I know institutions like Tasued, Eksued offer Bsc.ed degree
