The main similarity between chloroplasts and mitochondria is energy production.
Explanation:
The chloroplasts found in plant cells are home to chlorophyll, the green pigment used in photosynthesis. It is here that cells transform the energy from the sun into the chemical bonds in sugar molecules.
They say it’s “tree shedding” but each tree changes color by season depending on how much sunlight or darkness they get. Some change when they don’t get enough food.
