Answer 1

Wellll? I seem to remember that radishes do not have stems,they have a crown of leaves at the dorsal(top) of the "radish" (root).Sort of neck-less,until time to flower.Then a stalk emerges from the center of the crown.Therefore,not by the process of  elimination, I say reproduction.If I must pick only one.Stems do"circulation"of water and nutrients.I would say the pepper taste would be "immune".And "nervous",I swear I've seen stems wilt before my hungry eyes!!!Just kidding,sorta.
