Question: What is the leaf of a fern called?
Show answer
A frond.
The leaf of a fern is typically referred to as a frond. A fern frond is not like a conventional leaf; it is a complex structure that originates as a tightly coiled spiral known as a fiddlehead or crozier, due to its resemblance to the head of a violin. As it grows, the fiddlehead unrolls and expands into a frond.
Fronds are often large and divided, exhibiting a variety of patterns depending on the species of fern. They can be simple, with undivided leaf blades, or compound, with the leaf blade divided into smaller leaflets, or pinnae. Some ferns have even more complex structures, with the pinnae themselves being divided into even smaller segments, known as pinnules.
Each frond, in addition to its photosynthetic role, can produce spores, housed in structures called sporangia, typically found on the underside of the frond. These spores play a crucial role in fern reproduction. Ferns are unique in that they possess a two-stage life cycle involving alternating generations, with the frond-bearing plant known as the sporophyte generation.
