Answer:
When the sporangia break open, the spores are released and dispersed by the wind. If the spore lands in a suitable environment, it can grow into a tiny plant called a gametophyte. The gametophyte looks like a little, thin green plate. It does not have roots, stems or leaves.

Answer:
Spores are an asexual form of reproduction; the plant or fungus doesn't need to mate with another plant or fungus to form these particles. A parent plant sends out tiny spores containing special sets of chromosomes. These spores do not contain an embryo or food stores. Fertilizations of the spores takes place away from the parent, usually in a damp place. An embryo is formed and a new plant grows from it.
