Eukaryotic Exceptions. Most eukaryotic cells -- those that contain nuclei -- also contain mitochondria, but there are exceptions to this rule. Some parasitic protists, for example, take energy from their hosts and do not have mitochondria, as explained by an article in the Journal of Eukaryotic Microbiology. In humans, mature red blood cells, or erythrocytes, lack mitochondria as well, as reported by the Encyclopedia Britannica.
3. Plant and animals cells both contain vacuoles, but the vacuoles in plant cells are much larger than in animal cells. 4. Both plant and animal cells contain organelles called mitochondria that provide energy for the cell.However, plants also contain chloroplasts (generally in greater numbers than mitrochondria) that also produce energy for the cell, while animal cells do not.econd, the differences between eukaryotes like plant and animal cells and prokaryotes like bacteria are also important: 1. Prokaryotes generally do not contain membrane bound organelles such as mitochondria and chloroplasts, and instead produce their energy using proteins embedded in their plasma membrane.
