Correct Answer: Sorus
Solution : The correct answer is Sorus.
Sorus is the term given to a fern's cluster of sporangia (spore-producing structures) on its sporophyll (spore-bearing leaf). Sori are generally brown or orange, and their role is to discharge spores. As sporangia in a sorus reach maturity, they expel their spores into the air. The spores are incredibly tiny and light, and they may be transported for vast distances by the wind.
