I've been debating with my friends whether or not corn kernels are considered to be fruits or vegetables or nuts. To my knowledge, a fruit is a sweet "bubble" (in that it's a membrane with a fleshy interior) of a plant's seed (they remind me of pomegranate seeds). A vegetable is part of a plant that is eaten but not part of the seed. I was under the impression that nuts were only from a specific "branch" of plant evolution that is predominantly trees. This information would lead me to believe it is isn't any of them. Looking into it myself, I learned the word aril, but I'm not sure if corn's kernels are like that, either. It doesn't sound like it fits the criteria of that, or any of them.
Taking up from there, I'm a bit confused on what corn should be called. Do we have a name for corn like we do everything?
