An incomplete flower lacks one or more layers. An imperfect flower is lacking either the pistil or stamens. A regular flower is radially symmetrical. Examples include cucumber, peapod, walnut, tomato, orange, cherry, apple, dandelion, and maple helicopter. There are a number of types of simple fruit, each with its own official name.
Aggregate fruits arise from several ovaries in one flower.
Examples include raspberry and strawberry. Multiple fruits arise from ovaries in several, tightly-clustered flowers which grow together into one fruit. Examples include pineapple, mulberry, and breadfruit. Angiosperm Life Cycle Angiosperms have alternation of generations with the 2n sporophyte being the dominant generation. The ovaries, which are the equivalent of megasporangia, produce megaspores which grow into female gametophytes, each of which then produces an egg.
