plant cycle

 First, the the plants alternate in each generation. They all for the most part are tracheophytes which are vascular plants. Meaning they have vascular tissue as opposed to bracheophytes The sporophyte produce spores. It also uses meiosis to make the spores. This is the only time that meiosis is used in the life cycle. Then the spore grows into the Gametophyte. This process by mitosis is still haploid. This generation is the sexual generation. The gametophyte makes gametes. This forms a zygote. Then the cycle repeats.
