... Plants reproduce sexually, often relying on pollinators to bring sperm and egg together. The sporophyte (diploid) develops from the zygote by mitosis; it consists of roots, stems, leaves, and flowers Meiosis of cells within flowers produces the small haploid gametophytes, which in turn produce eith ...

The Dawn of Flowering Plants
... Flowering plants produce seeds encased in a protective covering, or carpel. If we cut into a fruit (e.g., apple, grape, tomato), we will see carpels with seeds. Such plants are called angiosperms, meaning “covered seed.” They contrast with more primitive plants like ferns, which reproduce by spores, ...

Flowering plant
The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants. Angiosperms are seed-producing plants like the gymnosperms and can be distinguished from the 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 ancestors of flowering plants diverged from gymnosperms around 245–202 million years ago, and the first flowering plants known to exist are from 160 million years ago. They diversified enormously during the Lower Cretaceous and became widespread around 120 million years ago, but replaced conifers as the dominant trees only around 60–100 million years ago.
