Why are the chloroplast and the mitochondria designed the way they are.

The mitochondria and the chloroplast are designed for efficiency. The chloroplast has a big surface their for it can let in more sun light witch brings in energy rich sugar called glucose.

The mitochondria also is efficient because the inner membrane has a large surface area and the larger the surface area the faster the glucose can be turned into ATP a molecule on energy. This energy in stored in side.

Both the mitochondria and the chloroplast organelles were designed with efficiency in mind.

see the photo the more thylakolds the more glucose can be made.
