stem

stem, supporting structure of a plant, serving also to conduct and to store food materials. The stems of herbaceous and of woody plants differ: those of herbaceous plants are usually green and pliant and are covered by a thin epidermis instead of by the bark of woody plants. There is relatively more pith in herbaceous stems, and the cambium, which increases the diameter of woody stems, is usually almost inactive; it is therefore characteristic of herbaceous stems that, although they increase in height, their increase in diameter is small. Most herbaceous plants are annuals; some have specialized underground stems (see bulb, corm, rhizome, and tuber) that store food and enable the plant to survive unfavorable growing conditions. Aerial stems may be specialized as tendrils, thorns, or runners (stolons); another specialization is the fleshy, moisture-retaining stem of many arid-land plants (such as most cacti and other succulents). Aerial stems are usually erect; however, in the climbing plants they require support and in others (e.g., melons) they are prostrate. The vascular system in the stem consists chiefly of xylem (upward-conducting) and phloem (downward-conducting) tissue, usually in vascular bundles arranged concentrically on either side of the cambium—the xylem (wood) inside, the phloem outside. In monocotyledonous plants, which generally lack cambium, the bundles are scattered throughout the stem tissue. The sap ducts are formed of elongated cells joined end to end; in the xylem the cell ends dissolve away completely to form continuous tubes and in the phloem they develop perforations and are called sieve plates. Herbaceous stems are marked externally by leaf and bud nodes; woody stems also bear lenticels (pores for transpiration), scars where leaves, twigs, and fruits have dropped off, and bud scars. The annual extension growth of a woody stem develops from a terminal bud usually protected by bud scales or stipules; when the scales fall away, a characteristic bud scar remains. The sap of certain stems contain gums, latexes, and resins used commercially; many are the source of wood of great economic importance.

STEM

STEM, also theme. A term in GRAMMAR and WORD-FORMATION for a ROOT plus the element that fits it into the flow of language. Stems are basic to such inflected languages as Latin and rare in analytic languages like English. In Latin, the root am (love) and a thematic vowel -a- make up the stem ama-, to which appropriate inflections are added: -s in amas thou lovest, -t in amat he/she/it loves. The only stems in present-day English are acquisitions from Latin and Greek. Such stems have no syntactic role, but often decide the spelling and sometimes the pronunciation of derivatives: because negative and auditory derive from Latin negare to deny, audire to listen, their stems are negat- and audit-. Spellings like *negitive and *audatory are therefore not possible. Whereas the rhythm of Latin makes the quality and quantity of all stem vowels clear, the rhythm of English often does not do so, reducing the vowels to a schwa and therefore limiting sound–spelling correspondences. See THEMATIC VOWEL.

stem

stem The part of a plant that usually grows vertically upwards towards the light and supports the leaves, buds, and reproductive structures (see illustration). The leaves develop at the nodes and side or branch stems develop from buds at the nodes. The stems of certain species are modified as bulbs, corms, rhizomes, and tubers. Some species have twining stems; others have horizontal stems, such as runners. Another modification is the cladode. Erect stems may be cylindrical or angular; they may be covered with hairs, prickles, or spines and many exhibit secondary growth and become woody (see growth ring). In addition to its supportive function, the stem contains vascular tissue that conducts food, water, and mineral salts between the roots and leaves. It may also contain chloroplasts and carry out photosynthesis.

stem

stem Main, upward-growing part of a plant that bears leaves, buds and flowers, or other reproductive structures. In vascular plants, the stem contains conducting tissues (xylem and phloem). In flowering plants, this vascular tissue is arranged in a ring (in dicotyledons) or scattered (in monocotyledons). They may be modified into underground structures (rhizomes, tubers, corms, bulbs). Stems vary in shape and size from the thread-like stalks of aquatic plants to tree-trunks.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

Notes:
  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
