Knowra Ginkgo biloba Ginkgo biloba Ginkgo biloba is a long-lived deciduous tree native to China and the sole living species of Ginkgophyta. Its fan-shaped leaves and unusually resilient lineage distinguish it among living trees.
Ginkgoales : An order of seed plants that includes living ginkgo and extinct relatives known from fossils. Ginkgo biloba is the sole living member of this seed-plant order.
Motile sperm : Sperm cells capable of moving through liquid using flagella. Ginkgo is one of the few living seed plants whose sperm swim to the egg.
Ginkgo fossils : Fossil leaves, wood, and reproductive structures documenting ginkgo relatives across deep time. Fossils reveal that ginkgo-like plants were once far more diverse and widespread.
Ornamental tree : A tree planted primarily for its appearance, shade, or contribution to designed landscapes. Ginkgo’s tolerance of urban conditions and distinctive foliage make it a common street tree.
Atomic bombing of Hiroshima : The United States’ atomic bombing of Hiroshima, Japan, on August 6, 1945. Several ginkgo trees near the blast survived and later became symbols of endurance.
Ginkgophyta : A division of seed plants represented today by Ginkgo biloba and formerly by diverse fossil groups. This ancient division contains the species and its extinct relatives.
Ovule : A plant structure containing the female reproductive cells that can develop into a seed after fertilization. Ginkgo ovules receive pollen and support fertilization before becoming seeds.
Permian : A geologic period lasting from about 299 to 252 million years ago. Ginkgo-like fossils extend the lineage’s history back to the Permian.
Ginkgo biloba extract : A preparation made from ginkgo leaves, commonly standardized for flavonoids and terpene lactones. Leaf extracts are sold as supplements and studied for possible effects on cognition and circulation.
Tree of life : A widespread cultural symbol linking life, continuity, ancestry, and renewal. Ginkgo’s longevity and persistence have made it a recurring emblem of endurance.
