Detailed explanation-1: -Pine tree. Conifers are cone-bearing seed plants which develop their seeds inside cones.
Detailed explanation-2: -Conifers grow cones to reproduce instead of flowers or fruits. Scales grow on the outside of the cones. Some species of conifer grow male and female cones on the same tree, while others grow male and female cones on separate trees. The male cones, which are smaller than the female cones, produce pollen.
Detailed explanation-3: -Gymnosperms – seed plants with cones Gymnosperms are seed plants but their seeds are held in cones. Next time you pick up a pine cone, look for loose seeds inside. Male cones make pollen, which is carried to female cones by the wind.
Detailed explanation-4: -Conifers are seed plants, and like most other seed plant groups they have wood, megaphyllous leaves, and of course seeds. These seeds are typically produced in woody cones, though the cones of some conifers are reduced to such a degree that they are no longer recognizable as such.
Detailed explanation-5: -Pinaceae cones The members of the pine family (pines, spruces, firs, cedars, larches, etc.) have cones that are imbricate (that is, with scales overlapping each other like fish scales). These pine cones, especially the woody female cones, are considered the “archetypal” tree cones.
