Why do producers contain the multiple mitochondria organelles along with chloroplasts?

Question

Concerning Biology

Answer 1

All eukaryotes have mitochondria. Plants need mitochondria to carry out oxidative respiration.

Answer 2

I'm not sure of the exact nature of your question. If you mean why are there mitochondria at all, then it's simple. The reason is the same as why non-photosynthetic organisms have mitochondrion: food (energy/ATP). Being able to synthesise foods meaning nothing if you are unable to use it.

However, I never heard of mulitple mitochondria in any organism (not part of a birth defect) so I couldn't tell you that answer.
