In [[botany]], the '''shoot''' is one of two primary sections of a [[plant]]; the other is the [[root]]. The shoot refers to what is generally the upper portion of a plant, and consists of [[plant stem|stems]], [[leaf|leaves]], [[flower]]s, and [[fruit]]s. It is derived from the embryonic [[epicotyl]], the portion of the [[embryo]] above the point of attachment to the [[seed]] leaves ([[cotyledon]]s).
In the shoot, [[water]] and [[nutrient]]s are transported from the root to the leaves in conducting [[biological tissue|tissue]] called [[xylem]], which consists primarily of [[tracheid]]s and [[vascular tissue|vessel]] members. Photoassimilates are carried away from mature leaves in conducting tissue called [[phloem]], which is mainly made up of [[sieve]] cells and sieve tube members.
In everyday speech, shoots are often confused with stems. Stems, which are a critical component of shoots, provide an axis for buds, fruits, and leaves.

A shoot may also refer to the new growth of a plant stem.
