It claims a banana isn't technically living, but a banana has living cells so I'm not sure how accurate that is. I'm not sure when they're all considered 'dead' after harvesting though - maybe some wiggle room there.

My understanding is that picked fruits and veg are still alive [1], and often respirating [2]. This is a big component in figuring out how to refrigerate them at the optimal temperatures and atmospheric makeup.
