An inflorescence is a flowering stem. The term is most used for a group or cluster of flowers arranged on a stem. An inflorescence is the reproductive portion of a plant; each plant bears its flowers in a specific pattern.
Whereas gymnosperms are mostly wind-pollinated, flowering plants are mostly pollinated by insects. There are some exceptions to this, for instance grasses are wind-pollinated. However, as a general rule, flowering plants rely on animals for their pollination.
