How are evergreen plants with woody stems having naked seed classified?

The correct answer is D, Gymnosperms. The name comes from the Greek words for naked and seed: gymnosperms bear seeds that are not enclosed in a fruit, and most of them are woody, evergreen trees. Gymnosperms are seed plants without flowers. Their seeds develop exposed on the scales of cones, as in pines. Most are perennial, evergreen and woody, with needle-like or scale-like leaves that help them survive cold and dry conditions. Common examples are pine, deodar, fir, spruce, cycas and ginkgo, and the giant redwoods and sequoias are among the tallest trees on Earth. They supply softwood timber, resin and turpentine. Option A is wrong because angiosperms are flowering plants whose seeds are enclosed inside a fruit. Option B is wrong because monocotyledons are a group within the angiosperms, such as grasses and palms, so their seeds are also covered. Option C is wrong because pteridophytes, such as ferns and horsetails, have roots, stems and leaves but produce no seeds at all, reproducing by spores. Exam tip: gymnosperms = naked seeds, cones, no fruit; angiosperms = seeds in a fruit.
