Monocercomonoides is a type of protist, which is a diverse group of eukaryotic microorganisms. It, therefore, appears likely that based on these five cell types, mammalian mitochondria contain 2. Its closest relatives still have small mitochondria, suggesting that it jettisoned the organelles fairly recently in evolutionary terms. A eukaryote is a cell or organism that possesses a clearly defined nucleus. Along with the similar parabasalid flagellates, they harbor the symbiotic bacteria that are responsible for breaking down cellulose . PA. V – A biossíntese celular em Monocercomonoides sp. Abstract.

The discovery that the protist Monocercomonoides exilis completely lacks mitochondria demonstrates that these organelles are not absolutely essential to. Looking at the tree for eukaryotes, what can you conclude about the Monocercomonoides?The notion that mitochondria cannot be lost was shattered with the report of an oxymonad Monocercomonoides exilis, the first eukaryote arguably without any mitochondrion. A mitochondrion is a tiny organelle that is typically round to oval and 0. Difficult. The organelles were then renamed “mitochondria” by Carl Benda twelve years later. 1. The protist Monocercomonoides, an inhabitant of vertebrate digestive tracts, appears to be an exception; it has no mitochondria and its genome contains neither genes derived from mitochondria nor nuclear genes related to mitochondrial maintenance.
