Sure! Self-pollination is simply using the pollen from a mature plant to pollinate itself (select a plant, grab the pollen, and drag it to the same plant). Cross-pollination is the process of pollinating a plant with the pollen from a different plant. If the two plants involved are identical, you will get seeds that will grow more of that kind of plant. If the two plants are different in any way, you will get seeds for a new type of plant. The difference may be only in the type of flower, the type of plant, or both.
Cross-pollinating is the only way to discover new plant species. You have to be careful when cross-pollinating, though. The hybrid species produced by cross-pollinating may be too fragile to survive in the lower-level soils. I recommend that you plant only one seed in a "batch" of seeds obtained by cross-pollination, to make sure that the plant will survive, before planting the rest of them.
