Further, pine-cones were regarded as symbols or rather instruments of fertility.
Sold by weight, the chestnuts are scooped up into brown paper bags or cones.
Pine cones stay warmer than the needles around them.
And hungry insects have heat sensors that spot the cones.
cones in each half of the retina are adapted to produce different light-filtering pigments.
The receptors of the former are the rods and cones that you all learned about in middle school.
Aspects such as the causal structure of spacetime and the global properties of light cones are crucial factors.
Question two is true if the mountains in question are volcanic in nature, especially cinder cones.
The cones were made up of sandstone, adobe, and pebbles.
The cells that detect light here, called cones, are responsible for all high-resolution vision.
British Dictionary definitions for cones
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: 1/3πr²h, 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
a small cone-shaped bollard used as a temporary traffic marker on roads
Also called retinal cone. any one of the cone-shaped cells in the retina of the eye, sensitive to colour and bright light
(transitive) to shape like a cone or part of a cone
C16: from Latin cōnus, from Greek kōnus pine cone, geometrical cone
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.
