see synonyms of cone
a geometric solid consisting of a plane base bounded by a closed curve, often a circle or an ellipse, every point of which is joined to a fixed point, the vertex, lying outside the plane of the base. A right circular cone has a vertex perpendicularly above or below the centre of a circular base. Volume of a cone: 13πr2h, where r is the radius of the base and h is the height of the cone
a geometric surface formed by a line rotating about the vertex and connecting the peripheries of two closed plane bases, usually circular or elliptical, above and below the vertex
See also conic section
anything that tapers from a circular section to a point, such as a wafer shell used to contain ice cream
the reproductive body of conifers and related plants, made up of overlapping scales, esp the mature female cone, whose scales each bear a seed
a similar structure in horsetails, club mosses, etc
. Technical name: strobilus

see synonyms of cone
a flat-based, single-pointed solid formed by a rotating straight line that traces out a closed-curved base from a fixed vertex point that is not in the same plane as the base; esp., one (right circular cone) formed by tracing a circle from a vertex perpendicular to the center of the base (also formed by rotating a right triangle 360° with either leg as the axis, or by rotating an isosceles triangle 360° with the altitude as the axis)
the surface of such a solid
a similar unbounded surface extending outward in both directions from a point: it is formed by rotating in an elliptical or circular pattern a straight line that always passes through this point
any object or mass shaped like a cone
; specif.,

3.  Botany
a reproductive structure of certain nonflowering plants, consisting of an elongated central axis upon which are borne overlapping scales, bracts, sporophylls, etc., usually in a spiral fashion, and in which are produced pollen, spores, or ovules; strobilus: cones are found in cycads, conifers, club mosses, horsetails, etc.
any similar structure, as the catkin of hops
4.  Zoology
any of the flask-shaped cells in the retina of most vertebrates, sensitive to bright light and color

b. A right circular cone.
a. The figure formed by a cone, bound or regarded as bound by its vertex and a plane section taken anywhere above or below the vertex.

3. Botany
a. A unisexual reproductive structure of most gymnospermous plants, such as conifers and cycads, typically consisting of a central axis around which there are scaly, overlapping, spirally arranged sporophylls that bear either pollen-containing structures or ovules.
b. A similar, spore-producing structure of club mosses, horsetails, and spikemosses.
c. A reproductive structure resembling a cone, such as the female inflorescence of a hop plant or the woody female catkin of an alder.
4. Physiology One of the photoreceptors in the retina of the eye that is responsible for daylight and color vision. These photoreceptors are most densely concentrated in the fovea centralis, creating the area of greatest visual acuity. Also called cone cell.
