Solution:
Yes, both single called and multicellular eukaryotes are known that have no mitochondria. all prokaryote cells survive just fine without any organelles. There are cells with no mitochondria that can survive just fine because they are unicellular such that they don’t need mitochondria such us bacteria. While,
Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.
