The main, often long or slender part of a plant that usually grows upward above the ground and supports other parts, such as branches and leaves. Plants have evolved a number of tissue arrangements in the stem. Seedless vascular plants (such as mosses and ferns) have primary vascular tissue in an inner core, a cylindrical ring, or individual strands scattered amid the ground tissue. In eudicots, magnoliids, and conifers, the stem develops a continuous cylindrical layer or a ring of separate bundles of vascular tissue (including secondary vascular tissue) embedded in the ground tissue. In monocots and some herbaceous eudicots, individual strands of primary vascular tissue are scattered in the ground tissue.
The inner core of certain organs or body structures, such as the marrow of bone.
The tissue so formed
Of or like an aphorism
Having the nature of an epigram; terse, witty, etc.
Obscure in meaning; enigmatic
Precisely meaningful; forceful and brief:
Forceful or powerful; strong; energetic
(Geology) The central portion of the earth below the mantle, beginning at a depth of about 2,900 kilometers (1,800 miles) and probably consisting of iron and nickel. It is made up of a liquid outer core and a solid inner core.
A difficult problem; puzzling thing
A solution of such a substance or oil in alcohol
The central idea; the essence.
A conventional two-lobed representation of the heart, usually colored red or pink.
The quality or condition of being important; significance.
Marrow is defined as an innermost, choice part, especially the fatty tissue inside bones.
The edible flesh of animals, especially that of mammals as opposed to that of fish or poultry.
(Biol.) The central, usually spherical or oval mass of protoplasm present in most plant and animal cells, containing most of the hereditary material and necessary to such functions as growth, reproduction, etc.
Strong, deeply felt emotion conveyed by a speaker, performer, or artist:
The capacity to resist attack; impregnability:
Significance or importance:
Effective legal or binding force; validity
The inner, usually edible seed of a nut or fruit stone.
A small piece
The pure, highly concentrated essence of a thing.
A plant part that usually grows underground, secures the plant in place, absorbs minerals and water, and stores food manufactured by leaves and other plant parts. Roots grow in a root system. Eudicots and magnoliids have a central, longer, and larger taproot with many narrower lateral roots branching off, while monocots have a mass of threadlike fibrous roots , which are roughly the same length and remain close to the surface of the soil. In vascular plants, roots usually consist of a central cylinder of vascular tissue, surrounded by the pericycle and endodermis, then a thick layer of cortex, and finally an outer epidermis or (in woody plants) periderm. Only finer roots (known as feeder roots) actively take up water and minerals, generally in the uppermost meter of soil. These roots absorb minerals primarily through small epidermal structures known as root hairs. In certain plants, adventitious roots grow out from the stem above ground as aerial roots or prop roots, bending down into the soil, to facilitate the exchange of gases or increase support. Certain plants (such as the carrot and beet) have fleshy storage roots with abundant parenchyma in their vascular tissues.
An inclination or tendency of a specified kind:
Abstract substance or character.
The main claim or most important aspect of a complaint against a defendant.
The most central and material part
A tissue in vascular plants that carries water and dissolved minerals from the roots and provides support for softer tissues. Xylem consists of several different types of cells: fibers for support, parenchyma for storage, and tracheary elements for the transport of water. The tracheary elements are arranged as long tubes through which columns of water are raised. In a tree trunk, the innermost part of the wood is dead but structurally strong xylem, while the outer part consists of living xylem, and beyond it, layers of cambium and phloem.
An area of dense population:
The quality or state of being inward
