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.

A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
[3] [2] Each primary Kyuranger carries a Seiza Blaster (セイザブラスター, Seiza Burasutā, Constellation Blaster) gauntlet, which they can use to transform, access their Kyutamas' power, [2] [4] and perform the All-Star Crash (オールスタークラッシュ, Ōru Sutā Kurasshu), Kyuren All-Star Crash (キ ...
Parenchyma is a versatile ground tissue that generally constitutes the "filler" tissue in soft parts of plants. It forms, among other things, the cortex (outer region) and pith (central region) of stems, the cortex of roots, the mesophyll of leaves, the pulp of fruits, and the endosperm of seeds.
While leaves and stems of perennial herbs die down at the end of the growing season the root often persists for many years or even the entire life. [1] Perennial herb species belonging to the dicotyledon group (also known as perennial forbs ) are characterized by secondary growth , which shows as a new growth ring added each year to persistent ...
Cross-section of a flax plant stem: 1. Pith 2. Protoxylem 3. Xylem I 4. Phloem I 5. Sclerenchyma 6. Cortex 7. Epidermis. In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. [1]
There are also many wild edible plant stems. In North America, these include the shoots of woodsorrel (usually eaten along with the leaves), chickweeds, galinsoga, common purslane, Japanese knotweed, winter cress and other wild mustards, thistles (de-thorned), stinging nettles (cooked), bellworts, violets, amaranth and slippery elm, among many others.
In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as Cuscuta. [1] There are many plants that have tendrils; including sweet peas, passionflower, grapes and the Chilean glory-flower. [2]
