both refer to movie chains (i.e., Loews, AMC Theatres) with movie theatres that screen more than one film at a time, as opposed to single-screen theatres. A multiplex has from 2 up to 16 screens, a megaplex has 16 or more screens; plex is the abbreviation for a multiplex theatre.
A morula (Latin, morus: mulberry) is an early stage embryo consisting of cells (called blastomeres) in a solid ball contained within the zona pellucida.
Morus, a genus of flowering plants in the family Moraceae, comprises 10â16 species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. The closely related genus Broussonetia is also commonly known as mulberry, notably the paper mulberry, Broussonetia papyrifera. Mulberries are fast-growing when young, but soon become slow-growing and rarely exceed 10â15 metres (30â50 ft) tall.
