IPA: //maɪkroʊspəˈrɒfɪl//
KK: /maɪkroʊspəˈrɒfɪl/
A leaf-like structure that produces small spore cases called microsporangia.
The microsporophylls of the plant are essential for its reproduction.
Microsporophyll → It is formed from "micro-" (from Greek "mikros", meaning small) and "sporophyll" (from Greek "spora", meaning seed or spore, and "phyllon", meaning leaf). The word refers to a small leaf that bears or produces spores.
Think of 'small' ('micro-') leaves that produce 'spores' ('sporophyll') — that's what a microsporophyll is.
