Alkanes are an example of saturated compounds. An unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively.Saturated and unsaturated compounds need not consist only of a carbon atom chain.n unsaturated compound is a chemical compound that contains carbon-carbon double bonds or triple bonds, such as those found in alkenes or alkynes, respectively.

Mitochondria Have DNA. Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function. A double membrane surrounds both mitochondria and chloroplasts, further evidence that each was ingested by a primitive host.
1 Eukaryotic cells have membrane-bound organelles. 2  Prokaryotic cells have only one organelle: the ribosomes. 3  Ribosomes look different in size and shape in prokaryotes than eukaryotes. 4  Eukaryotic has nucleus, the control center of the cell.
