Detailed explanation-1: -Most conifers produce a seed cone comprised of bracts spirally arranged about a central axis, with two ovules on each bract, each ovule developing a single seed with attached seedwing. When the seed cones mature and open, these seeds are shed and dispersed by wind.
Detailed explanation-2: -Gymnosperms are not characterized by Winged seeds.
Detailed explanation-3: -The seeds of Pinus are mostly small and winged, and are anemophilous (wind-dispersed), but some are larger and have only a vestigial wing, and are bird-dispersed.
Detailed explanation-4: -Wind dispersal Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have ‘winged’ seeds.
