What is the dominant generation in gymnosperms and how does it contribute to the reproductive cycle of these plants?

The dominant generation in gymnosperms is the sporophyte, which produces spores through meiOSis. These spores develop into gametophytes, which produce gametes through mitosis. The gametes then fuse to form a zygote, which develops into a new sporophyte, completing the reproductive cycle of gymnosperms.
