A leaf-like part of a plant that produces large spores.
The megasporophyll is essential for the reproduction of certain plants.
Megasporophyll → It is formed from "mega-" (from Greek "megas", meaning large) and "sporophyll" (from Greek "spora", meaning seed, and "phyllon", meaning leaf). The word refers to a large leaf that bears seeds or spores, typically found in certain plants.
Think of 'large' ('mega-') leaves that produce 'seeds' ('spora') — that's what a megasporophyll is.
