Post-fertilization events: endosperm, embryo, seed, and fruit
Mature seeds can be non-albuminous (no endosperm present), or albuminous (retains endosperm). In some cases, like black pepper and beets, remnants of the nucellus can be found (perisperm). The micropyle remains as a pore in the seed coat, to allow the exchange of water and oxygen with the environment.
