Pine cones and flowers both include places where the ovule can be kept safe and places where pollen can be produced and released. Cones are relatively simple, while flowers add more kinds of parts mostly designed to allow helpful interactions with pollinators, as is the case for petals. Also, flowers often include both male and female parts while cones for male and female parts are separate structures.
