Detailed explanation-1: -One of the main differences between the ETCs of chloroplasts and the mitochondria is their location with the organelles. In chloroplasts, the ETC is embedded in the thylakoid membrane whereas in the mitochondria, the ETC is embedded in the inner mitochondrial membrane.

Detailed explanation-2: -Like mitochondria, chloroplasts are surrounded by two membranes. The outer membrane is permeable to small organic molecules, whereas the inner membrane is less permeable and studded with transport proteins.

Detailed explanation-3: -Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.

Detailed explanation-4: -The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation. It occurs in mitochondria in both cellular respiration and photosynthesis.
