The question you have to answer is the seed contained in a fruit. Although you almost never see them, the banana does contain seeds (though non-fertile). So Angiosperm is the answer.One curiosity of bananas is that because of their high potassium content, shipments have been known to set off radiation detectors at the ports! For K40 decays to Ar40 with the emission of a radiation particle. But continue to enjoy them!
