Whilst I'm all for scientific endeavour and wholistic understanding, is it really the role of humans to act as custodians to manipulate a Kingdom that has existed well prior to our species' time on this planet to serve its own interests? The humble concept of co-existence doesn't seem present, here.

Where did you see ‘manipulation’?

If a chloroplast has a bit of different DNA - is it similar to mitochondria?

Yes, in terms of they are their own plastids with their own DNA and protein products. The prediction is that they formed a symbiotic relationship with other cells, thus getting engulfed and retaining their separate genome. Is the DNA in Chlorplasts and Mitochondria related? No. They come from separate plastids.

@@Fearsomemitchy I had to look up some of the words. So mitochondria and chloroplasts have a similar history but the way they produce energy is different and they are in very different branches of the circle of genetic relationships. Thank you!

@@susanne5803 - chloroplasts and Mitochondria were completely unrelated small cells which ended up getting engulfed by larger cells, the larger cell didn’t eat them or kill them, instead the larger cell protected them from harm, the chloroplast/mitochondria was then free to create energy via Photosynthesis/Respiration. It was a mutually beneficial relationship. Thus it stayed. This is why choloplasts and Mitochondria still have their own DNA inside of them, this is what is left from the original DNA when they were their own cells millions of years ago.
