before_revision: The flowering plants, also known as Angiospermae (), or Magnoliophyta (), are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Like gymnosperms, angiosperms are seed-producing plants . They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds , and the production of fruits that contain the seeds. Etymologically, "angiosperm" literally means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words ('case') and ('seed') . The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms during the Carboniferous, over 300 million years ago, with the earliest record of angiosperm pollen appearing around 134 million years ago. The first remains of flowering plants are known from 125 million years ago. They diversified extensively during the Early Cretaceous, became widespread by 120 million years ago, and replaced conifers as the dominant trees from 60 to 100  million years ago.

Like gymnosperms, angiosperms are seed-producing plants , but regarding seeds, they differ from gymnosperms in their production of three critical structures: flowers; endosperm within their seeds ; and fruits that encase their seeds. Etymologically, "angiosperm" comes from the Greek words ('case') and ('seed') ; the term means a plant that produces seeds encased within an enclosure, say a 'fruit'. In other words, a fruiting plant.
