Which phylum contains flowering plants?

The correct choice is Phylum Anthophyta, as this phylum is specifically characterized by flowering plants, also known as angiosperms. This group of plants is distinguished by the presence of flowers and fruit, which aid in reproduction and seed dispersal. Anthophyta encompasses a vast diversity of plants, including trees, shrubs, and herbs, that have developed intricate mechanisms for pollination and seed development.

While Gymnospermae and Angiospermae are often considered synonymous with flowering plants, the formal classification defines Anthophyta as the specific phylum that includes them. Gymnospermae refers primarily to non-flowering seed plants, such as conifers, that produce seeds exposed on cones rather than enclosed in a fruit. Chlorophyta, on the other hand, is a phylum of green algae, which does not include any flowering plants at all. Thus, Anthophyta is the best representation of the group consisting of flowering plants.
