It helps if you know a little bit about the origins of these words. The easiest to remember is that the "-phyte" part of sporophyte means "plant". So the sporophyte is always diploid and is the life-phase that produces spores (which are haploid). The sporangium is the container that holds and releases the spores (the "-angium" part is taken from a Greek word meaning container or vessel; it becomes "-angia" in the plural)



In some texts you will see the terms "microspore" and "megaspore". These are easier to remember because everyone knows that micro means small and mega means large. They are used for the small reproductive cells (pollen) and the relatively large ones (egg cells) in higher plants.
