Like the sporophytes of seed plants, those of ferns consist of:
* [[Plant stem|Stems]]: Most often an underground creeping [[rhizome]], but sometimes an above-ground creeping [[stolon]] (e.g., [[Polypodiaceae]]), or an above-ground erect semi-woody trunk (e.g., [[Cyatheaceae]]) reaching up to 20 m in a few species (e.g., ''Cyathea brownii'' on [[Norfolk Island]] and ''Cyathea medullaris'' in [[New Zealand]]).
* [[Leaf]]: The [[green]], [[photosynthesis|photosynthetic]] part of the plant. In ferns, it is often referred to as a [[frond]], but this is because of the historical division between people who study ferns and people who study seed plants, rather than because of differences in structure. New leaves typically expand by the unrolling of a tight spiral called a crozier or [[fiddlehead]]. This unckiangleying of the leaf is termed [[circinate vernation]]. Leaves are divided into three types:
** Trophophyll: A leaf that does not produce spores, instead only producing sugars by photosynthesis. Analogous to the typical green leaves of seed plants.
** [[Sporophyll]]: A leaf that produces spores. These leaves are analogous to the scales of pine cones or to stamens and pistil in gymnosperms and angiosperms, respectively. Unlike the seed plants, however, the sporophylls of ferns are typically not very specialized, looking similar to trophophylls and producing sugars by photosynthesis as the trophophylls do.
** Brophophyll: A leaf that produces abnormally large amounts of spores. Their leaves are also larger than the other leaves but bear a resemblance to trophophylls.
* [[Root]]s: The underground non-photosynthetic structures that take up water and nutrients from [[soil]]. They are always [[fibrous root system|fibrous]] and are structurally very similar to the roots of seed plants.
 
The gametophytes of ferns, however, are very different from those of seed plants. They typically consist of:
