Final answer:
Mitochondria and chloroplasts have a double membrane and are both involved in energy production.
Step-by-step explanation:
Mitochondria and chloroplasts have several structural similarities. They both have a double membrane, meaning they are surrounded by two layers of membranes. Additionally, both organelles are involved in energy production. Mitochondria produce ATP through cellular respiration, while chloroplasts produce ATP through photosynthesis.
