Gymnosperm Life Cycle.wmv (360p).mp4

This scientific video explains how life cycle is in gymnosperms which are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and Gnetales. For example in a pine tree which is also a gymnosperm, when the pollen from a male pine cone floats on the wind and reaches a female pinecone, it fertilizes cone so seeds can grow. I should mention here that a pine tree's seeds are not inside a fruit, like an apple but out in the air attached to a pinecone. When the seeds are ready the pine tree will drop the cone to the forest floor. Some may have a chance to sprout, grow and form young another pine tree.
