A 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.

By contrast, non-herbaceous vascular plants are woody plants that have stems above ground that remain alive, even during any dormant season, and grow shoots the next year from the above-ground parts – these include trees, shrubs, vines and woody bamboos. Banana plants are also regarded as herbaceous plants because the stem does not contain ...
Adventitious bud – a bud that arises at a point on the plant other than at the stem apex or a leaf axil. Axillary – an embryonic shoot which lies at the junction of the stem and petiole of a plant. Dormant – see "Latent bud". Epicormic – vegetative buds that lie dormant beneath the bark, shooting after crown disturbance [14] Flower bud –
Bark is present only on woody plants - herbaceous plants and stems of young plants lack bark. Tree cross section diagram. From the outside to the inside of a mature woody stem, the layers include the following: [20] Bark Periderm Cork (phellem or suber), includes the rhytidome; Cork cambium (phellogen) Phelloderm; Cortex; Phloem; Vascular ...
The upper angle between one part of a plant and another, e.g. the stem and a leaf. axile On an axis; of a placenta, on the central axis of the ovary. axillary Borne in or arising from the axil, usually referring to the axil of a leaf. axis The main stem of a whole plant or inflorescence; also, the line along which this stem extends.
The caudex of a tree fern resembles the trunk of a woody plant, but has a different structure. The caudex of Jatropha cathartica is pachycaul, with thickening that provides water storage. A caudex (pl.: caudices) of a plant is a stem, [1] but the term is also used to mean a rootstock [2] and particularly a basal stem structure from which new ...
The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots (monocots usually lack secondary growth). It is one of the plant's meristems – the series of tissues consisting of embryonic disk ...
Plant anatomy or phytotomy is the general term for the study of the internal structure of plants.Originally, it included plant morphology, the description of the physical form and external structure of plants, but since the mid-20th century, plant anatomy has been considered a separate field referring only to internal plant structure.
