Ferns come in various shapes and sizes, but they all have 3 major parts – the fronds, the rhizome, and the reproductive structures called sporangia.
The fronds, the rhizome, and the sporangia are 3 major parts of the fern. The fronds are the leaves of the fern. The rhizome is the stem of the fern plant. The sporangia are reproductive structures and are found in clusters (called sori; singular sorus) underneath the fronds.
