Detailed explanation-1: -Male pine cones produce pollen, which is like a powder. The male cones release their pollen, which is carried around the air by blowing wind, and hopefully to another female pine cone on a different pine tree. If the pollen reaches a female pine cone, this process is called pollination.
Detailed explanation-2: -But pine trees actually produce two kinds of cones: a female cone and a male cone. Cones are modified stems that have been retasked for reproduction. The female cone, which is larger than the male cone, consists of a central axis and a cluster of scales, or modified leaves, called strobili.
Detailed explanation-3: -In order for seeds to form, pollen from male cones needs to be transferred to female cones. Each tree produces both male cones and female cones. Instead of relying on insects such as bees to pollinate the female cones, pine trees rely on wind to blow the pollen from the male cone to the female cones.
