A sweet viscous secretion containing from 5% to 80% sugar, including glucose, fructose, and sucrose, produced by the stems, leaves, and flowers of angiosperms (flowering plants). Nectar is produced in structures called nectaries, which are usually at the base of the flower petals, but may be found also in parts of the stem or at the leaf bases. By attracting insects, nectar facilitates pollination. Nectars with over 15% sugar are used by honey bees to make honey.
