State

A complete flower carries four organ types arranged in whorls: sepals, petals, pollen-bearing stamens, and ovule-containing carpels.

Show

A stamen's anther produces pollen; a carpel's ovary at its base houses one or more ovules awaiting fertilization.

Watch for

Not every flower carries all four organ types — an incomplete flower can lack sepals, petals, or a whorl and still function.
