Is it true that the nectary is a glandular structure that produces nectar to attract pollinators?

A nectary is a glandular structure that produces nectar, a sweet fluid, to attract pollinators such as insects, birds, and bats. The nectar contains sugar and other compounds that provide energy and nutrition to the pollinators, encouraging them to visit the flower and transfer pollen from the anther to the stigma. Nectaries are typically located in flowers and can be found on the ovary, corolla, or other floral parts.
