In botany, a peduncle is a stalk supporting an inflorescence or a solitary flower, or, after fecundation, an infructescence or a solitary fruit. The peduncle sometimes has bracts (a type of cataphyll) at nodes. The main axis of an inflorescence above the peduncle is the rachis, which hosts flowers (as opposed to directly on the peduncle).

Because flowers facilitate plant reproduction, inflorescence characteristics are largely a result of natural selection. [3] The stem holding the whole inflorescence is called a peduncle. The main axis (also referred to as major stem) above the peduncle bearing the flowers or secondary branches is called the rachis.
Diagram of flower parts. In botany, floral morphology is the study of the diversity of forms and structures presented by the flower, which, by definition, is a branch of limited growth that bears the modified leaves responsible for reproduction and protection of the gametes, called floral pieces.
Flowers may be directly attached to the plant at their base (sessile—the supporting stalk or stem is highly reduced or absent). [2] [25] The stem or stalk subtending a flower, or an inflorescence of flowers, is called a peduncle. If a peduncle supports more than one flower, the stems connecting each flower to the main axis are called pedicels.
Peduncle (botany), a stalk supporting an inflorescence, which is the part of the shoot of seed plants where flowers are formed; Peduncle (anatomy), a stem, through which a mass of tissue is attached to a body Peduncle (arthropods), the base segments of an antenna; Caudal peduncle, in fish, the narrow part of the body to which the tail attaches
In the absence of a pedicel, the flowers are described as sessile. Pedicel is also applied to the stem of the infructescence. The word "pedicel" is derived from the Latin pediculus, meaning "little foot". [2] The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. [3]
Nectar disk – when the floral disk contains nectar secreting glands; often modified as its main function in some flowers. Pedicel – the stem or stalk that holds a single flower in an inflorescence. Peduncle – the part of a stem that bears the entire inflorescence, normally having no leaves, or the leaves having been reduced to bracts.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
