WEBSep 13, 2024 · Plant - Stem Structure, Function, Types: A plant body consists of stems, leaves, roots, flowers, fruits, and seeds. Stems are usually the main axis of a plant, leaves act as the primary site of photosynthesis, and roots absorb water and nutrients.
Plant stem - Wikipedia
WEBA stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, engages in photosynthesis, stores nutrients, and produces new living tissue.
