Seeds grow on top of the plants with out any covering which is why they are called gymnosprems. = = = =They ﻿ are also called naked seeds. These seeds produce in something called seed cones. When male sex germs mix with female sex germs the seed cone starts to grow.Not all of the conifers produce seed cones. The female structure of the conifer does not produce seed cones instead they have a berry like structure. Conifers first originated over 300 million years ago. They are mostly found in tropical forest.The male cone releases the pollen into the female parts by wind. The pollen fertilizes the female gamete. A fertilized female gamete develop into an embryo. A seed develops containing the embryo. Mature seeds drop to the floor from the cone. The seeds germinate and grow into a plant then the whole cycle begins again.The pollen found in conifers is transferred from male to female parts by wind. The pollen does not transfer by any insect or animal. Conifer pollen is able to move with the wind because they have these ear like flaps located inside the pollen. =
