The correct option is D Chaos chaos
Mitochondria are eukaryotic cell organelles involved in aerobic respiration. Mitochondria are absent from anaerobic cells and red blood corpuscles. A single tubular or often twisted mitochondria occurs in yeast, Microasterias, Trypanosoma and Chlorella. 20 to 24 mitochondria occurs in sperms, 300 to 400 in kidney cells, 500 to 1000 in liver cells, 50,000 in giant amoeba Chaos chaos and 500,000 in flight muscles cells of birds. Thus, the correct answer is option A.
