Answer 2

Answer:

The flowering plants, also known as Angiospermae,[6][7] or Magnoliophyta,[8] are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species.[9] Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion ("case" or "casing") and sperma ("seed").
