Morphology

megasporangium = sporangium (semi-transparent) = mega + sporangium

The word is clearly built from 'mega' + 'sporangium', but the biological sense is specialized rather than fully predictable from the components alone.

Etymology

Megasporangium comes from three parts: mega- 'large', spore 'a single cell that can grow into a new plant', and -angium 'container'. So a megasporangium is simply a 'large spore container', which explains why it is the plant structure that makes the big spores called megaspores.
