24. Spore

This is a picture of spores on ferns. Spores are located under the leaves of ferns. They are reproductive cells that do not need the help of another cell to become a gametophyte. There are more than 15,000 different species of ferns and they all use spores to help them reproduce. Spores are the products of meiosis in sporophytes. The spores in this picture are distributed to other areas by wind, water, or other natural forces.
