cone cell - wikipedia
cone cells or cones are photoreceptor cells in the retinas of vertebrate eyes (e.g. the human eye). they respond differently to light of different wavelengths and are thus responsible for color vision and function best in relatively bright light as opposed to rod cells which work better in dim light.

cone - wikipedia
a cone with a region including its apex cut off by a plane is called a "truncated cone"; if the truncation plane is parallel to the cone's base it is called a frustum.an "elliptical cone" is a cone with an elliptical base. a "generalized cone" is the surface created by the set of lines passing through a vertex and every point on a boundary (also see visual hull).

pine cones (herein referring only to the true cones) have a peduncle (stem) which attaches to the branch (usually the upper branches) of the tree and this continues through the entire length of the cone as the rachis (axis).multiple cone scales arise along the length of the rachis in a helical fashion to give the cone most its mass and characteristic external appearance.
