Mitochondria

Are mitochondria alive? They seem to perform all the nessecary life functions.

Thanks.

no they are not alive. According to a current theory, they were once living aerobic bacteria that was engulfed by an archean.
Why aren't they alive any more? because allthough they do have their own ribosomes and carry out protein synthesis, most of their proteins are imported from the cytoplasm. Some of their genes have moved to the nucleus in the course of evolution.

Yeah isnt that interesting? They basicly moved backward in terms of complexity.
