In plants, as with most animals, the male parts are associated with production of sperm, and the female parts are associated with eggs.
Thus, in angiosperms (flowering plants) and gymnosperms (plants with “naked seeds”), the male structures produce pollen (which contain sperm)
and the female structures have one or more ovaries (which contain eggs known as ovules).
We’ll skip over spore-producing plants, such as ferns and liverworts, because their life cycles are more complicated, but they too have male and female parts.
Some plants are indeed only male or only female.Ginkgo, kiwi, cannabis, and willow all have individuals that make only pollen or only seeds.
. In flowering plants, these structures can be borne together in a single bisexual flower, or the flowers can be only male (staminate) or only female (pistillate). Many of the most iconic flowers, such as roses, lilies, and tulips, are bisexual, and the female pistil is characteristically surrounded by the male stamens.
