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.
But blastula is a hollow structure, due to the presence of fluid-filled space called blastocoel. â¢ Trophoblast cells are present in blastula unlike in morula. â¢ Unlike in blastula, morula consists of an inner and outer cell masses. â¢ Duration of the formation of morula is lower than the formation of the blastula. During the embryonic development, zygote transforms to morula and then morula transforms to blastula. â¢ The cells inside the morula are larger than the cells that form blastula. â¢ The number of cells in blastula is larger than that in morula.
