Organizing and summarizing search results for youEudicots are a group of flowering plants that can be distinguished from other plant groups by the structure of their pollen. Their pollen grains have three colpi (grooves) paralleling the polar axis, which is referred to as triaperturate pollen. Other dicotyledons and the monocotyledons have monosulcate pollen (or derived forms): grains with a single sulcus. The number of pollen grain furrows or pores helps classify the flowering plants, with eudicots having three colpi (tricolpate), and other groups having one sulcus.4 Sources
