Question: A cluster of spore sacs on the under surface of a fern frond?

A cluster of spore sacs on the under surface of a fern frond is called a sorus (plural: sori). Sori are the reproductive units of ferns, containing numerous tiny sporangia, which produce and release spores. These spores are the fern's equivalent of seeds, and they allow ferns to reproduce without the need for flowers or fruits.

The arrangement, shape, and color of sori vary among fern species, and they can be useful for identifying ferns. Some ferns have sori that are round or oval, while others have sori that are linear or elongated. The sori may be covered by a protective indusium, a thin flap of tissue that protects the developing spores.

When the spores are mature, the sporangia dehisce, or burst open, releasing the spores into the air. The spores can then travel by wind or water to new locations, where they can germinate and grow into new fern plants.

Sori are an important part of the fern life cycle, and they play a crucial role in the reproduction of these fascinating plants.
