Conifer Cone

Cone (botany)

A cone, or in formal botanical usage a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like. The cones of Pinophyta contain the reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually ephemeral and much less conspicuous even at full maturity. The name 'cone' derives from Greek konos, which also gave name to the geometric cone. The individual plates of a cone are known as scales. In conifers where the cone develops over more than one year, the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale, is called an umbo, while the second year's growth is called the apophysis.

Conifer

Conifers are a group of vascular plants and a subset of gymnosperms. They are woody trees and shrubs, mostly evergreen with a regular branching pattern, reproducing with male and female cones, usually on the same tree. They are wind-pollinated and the seeds are usually dispersed by the wind. Taxonomically, they make up the division Pinophyta, also known as Coniferae. All extant conifers, except for the gnetophytes, are perennials with secondary growth. There are over 600 living species.

Cone

In geometry, a cone is a three-dimensional figure that tapers smoothly from a flat base to a point not contained in the base, called the apex or vertex.
