thats obviouse, I think he knew that. he was asking more specificaly what are they made of, what parts of a plant are they.
the most popular definition, or widely used is "a plant cultivated for its floral beauty."
I would not say cannabis falls under this category.
also flowers are usualy thought to have pedals around the reproductive organs with bright colors to help draw things to it, neither of which cannabis posses.
also flowers are though to have a sort of uniformity, or pattern. as in one flower is usualy about the same size, and template, they will have 6 pedals, all white and pink, I can go on, but I want to smoke...
this is why you will read some people calling them flowers, floral clusters, fruits, vegetables, herb, and a whole lot of other kind of plants.
cannabis is truly a one of a kind plant, one of the very few plants that have both males and females, and the only diodaciouse plant that can be sexed by looks alone.
The only plant to be able to smell and taste almost like anything else, the only plant that started civilization, has the possiblities to cloth, feed, and shelter all the world (and get them high too!!!) there ws even a car made completly of cannabis and ran completly on ethenol derived from hemp (made in the early 1900's by henry ford himself)
It seems if anything Pot wants us to know Its not like any other plnat, its special, therefor we need to make shit up, or use alot of words.
