Understand the role of mitochondria and chloroplasts in cells: Mitochondria are involved in cellular respiration, while chloroplasts are involved in photosynthesis.
Recognize the process of chemiosmosis: Both organelles use chemiosmosis to generate ATP, which involves the movement of protons across a membrane.
Identify the structure of mitochondria and chloroplasts: Both are surrounded by a double membrane, not a single membrane.
Clarify the electron source: Mitochondria obtain electrons from organic molecules, while chloroplasts obtain electrons from water during photosynthesis.
Note the by-products: Mitochondria release carbon dioxide, while chloroplasts release oxygen as a by-product of photosynthesis.
