Why Can Eukaryotes Survive Without Mitochondria?

Eukaryotes that use oxygen to optimize their energy production could not survive if their mitochondria were taken away. ... Since they have no mitochondria to complete aerobic respiration, all amitochondriate eukaryotes are anaerobic. Intestinal parasite Giardia lamblia, for example, is anaerobic and has no mitochondria.

Can eukaryotic cells survive without mitochondria?
