Meaning and Definition
A specialised leaf or bract that bears megasporangia, which produce megaspores, typically found in gymnosperms and some ferns.
In botany, a megasporophyll is the sporophyll (spore-bearing leaf) on which megasporangia develop. In flowering plants, this evolutionary concept is linked to the carpel. In cycads, it is often large and conspicuous, sometimes forming a structure like a seed cone.

FAQ
Frequently Asked Questions
In an evolutionary sense, the carpel of flowering plants is considered a highly modified megasporophyll. In living gymnosperms like cycads, they are distinct structures.
Yes, in plants like cycads, megasporophylls are often large, woody, and form conspicuous cones.
The opposite is a microsporophyll, which bears microsporangia that produce pollen (microspores).
No. They are a feature of vascular plants that produce two distinct types of spores (heterosporous plants), such as some ferns, all gymnosperms, and their evolutionary descendants, the angiosperms.

Mnemonic
Think: MEGA (large) + SPORO (spore) + PHYLL (leaf) = the leaf that makes the big spores (megaspores).
Conceptual Metaphor
A FACTORY FLOOR: The megasporophyll is the specialised production line where the female reproductive cells (megaspores) are manufactured.
