  2. 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 vertexSee also conic section

coned in Science

cone

[kōn]

A three-dimensional surface or solid object in which the base is a circle and upper surface narrows to form a point. The surface of a cone is formed mathematically by moving a line that passes through a fixed point (the vertex) along a circle.
A rounded or elongated reproductive structure that consists of sporophylls or scales arranged spirally or in an overlapping fashion along a central stem, as in conifers and cycads. For example, the familiar woody pinecone is actually the female cone, made up of ovule-bearing scales. The smaller male cones of the pine consist of thin overlapping microsporophylls. These produce pollen that is carried by the wind to fertilize ovules in the female cones. When the seeds in the female cones mature, the cones of many pine species expand to release them. In some pine species, cones release seeds only in response to the presence of fire. See also strobilus.
One of the cone-shaped cells in the retina of the eye of many vertebrate animals. Cones are extremely sensitive to light and can distinguish among different wavelengths. Cones are responsible for vision during daylight and for the ability to see colors. Compare rod.
