'''Frond''' is a term in botany that refers to the large, divided leaf of a fern, palm or cycad. The term is also used in a broader sense to describe any large, divided leaf.

== Overview ==

A frond is a large, usually divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group. Other botanists allow the term frond to also apply to the large leaves of cycads and palms (Arecaceae).

Fronds have particular terms describing their components. Like all leaves, fronds usually have a stalk connecting them to the main stem. In ferns, this stalk is called a [[stipe]]. The main, large part of the frond is called the [[blade]]. The blade may be simple, but is often divided into smaller leaflets, or [[pinnae]]. These leaflets may be further divided to form [[pinnules]].

== Structure and Function ==

Fronds are unique in their structure and function. They are typically large and divided, allowing for maximum photosynthesis. The structure of the frond also allows for efficient water and nutrient transport.

Fronds are also unique in their reproductive function. In many ferns, the underside of the frond contains [[sporangia]], which are structures that produce and release spores. These spores can then grow into new ferns.

== Types of Fronds ==

There are several types of fronds, including:

* '''[[Pinnate fronds]]''': These fronds have a central axis with leaflets arranged on either side, similar to a feather.
* '''[[Palmate fronds]]''': These fronds have leaflets that radiate out from a central point, similar to the fingers on a hand.
* '''[[Bipinnate fronds]]''': These fronds have leaflets that are further divided into smaller leaflets.
