A cone is an organ on conifers plants that contains the reproductive structures. The familiar woody cone is the female cone, which produces seeds. • The male cones, which produce pollen, are usually herbaceous and much less conspicuous even at full maturity. • The name cone derives from the fact that the shape in some species resembles a geometric cone. The individual plates of a cone are known as scales. • After ripening, the opening of pine cones is associated with their moisture content, cones are open when dry and closed when wet. • This assures that the small, wind disseminated seeds will be dispersed during relatively dry weather, and thus, the distance traveled from the parent tree will be enhanced. • A pine cone will go through many cycles of opening and closing during its life span, even after seed dispersal is complete. • This process occurs with older cones while attached to branches and even after the older cones have fallen to the forest floor. • The condition of fallen pine cones is a crude indication of the forest floor's moisture content, which is an important indication of wildfire risk. • Closed cones indicate damp conditions while open cones indicate the forest floor is dry. • Because of their widespread occurrence, conifer cones have been a traditional part of the arts and crafts of cultures where conifers are common. • Examples of their use includes seasonal wreaths and decorations, fire starters, bird feeders and toys. • For more videos, photos and blog posts like this please visit http://www.wholesomeday.com • Twitter: / wholesomeday • Tumblr: / wholesomeday • Pinterest: / wholesomed • Facebook: / wholesomeday
