Web[4] [5] The first two are all prokaryotes, single-celled microorganisms without a membrane-bound nucleus. All organisms that have a cell nucleus and other membrane-bound organelles are included in Eukarya and are called eukaryotes . Non-cellular life is not included in this system. WebBecause a eukaryotic cell’s nucleus is surrounded by a membrane, it is often said to have a “true nucleus.” The word “organelle” means “little organ,” and, as already mentioned, …

Membrane Bound Organelles in Cells - Study.com

WebThe endosymbiotic hypothesis for the origin of mitochondria (and chloroplasts) suggests that mitochondria are descended from specialized bacteria (probably purple nonsulfur bacteria) that somehow survived endocytosis by another species of prokaryote or some other cell type, and became incorporated into the cytoplasm. http://www.ruf.rice.edu/~bioslabs/studies/mitochondria/mitorigin.html civan raki
