In fact, birds are considered dinosaurs (they certainly descended from dinosaurs) and their cells have mitochondria, so we can be as sure as scientifically possible that dinosaurs indeed did have mitochondria.
Culturing a specimen allows for the identification of microorganisms present in the sample. This is important for diagnosing infections and determining appropriate treatment. It also helps in understanding the growth characteristics and antibiotic susceptibility of the organism.
Cellular respiration occurs in the mitochondria.
