Question

which anatomical feature of eukaryotes played the biggest role in their success in high levels of atmospheric oxygen? flexible cell membrane mitochondrion digestive vacuoles chloroplast well - developed cytoskeleton question 3 of 20 © macmillan learning

Explanation:

Mitochondria are the power - houses of the cell and carry out aerobic respiration, which is highly efficient in the presence of oxygen. Eukaryotes with mitochondria could utilize the high levels of atmospheric oxygen for energy production, contributing greatly to their success. Chloroplasts are related to photosynthesis, digestive vacuoles to digestion, flexible cell membranes are a general feature, and a well - developed cytoskeleton is related to cell structure and movement, but none are as directly related to oxygen - utilization as mitochondria.

Answer:

Mitochondrion
