Mitochondria differ from chloroplasts in that mitochondria a. contain three different membrane-bound compartments, whereas chloroplasts contain two. b. contain membrane folds called cristae, whereas chloroplasts contain disk-like vesicles in stacks called grana. c. produce glucose, whereas chloroplasts break glucose down. d. convert solar energy to chemical energy, whereas chloroplasts convert one form of chemical energy to another. e. are not found in plants, whereas chloroplasts are not found in animals.

Option B, contain membrane folds called cristae, whereas chloroplasts contain disk-like vesicles in stacks called grana.

Explanation:

Both Mitochondria and chloroplasts have double membrane surrounding the organelles thus option A is incorrect

A chloroplast is responsible for generating glucose while a mitochondria breaks down glucose to generate energy from it. Hence, option C is also in correct.

It is the chloroplast that converts solar energy to chemical energy (glucose) , while mitochondria converts one form of chemical energy (glucose) to another form of chemical energy. Hence option D is also incorrect.

Chlorophyll are found in plants and mitochondria is found in both plants and animal cells and hence option E is incorrect

Mitochondria have cristae which are nothing but the membrane folds while the chloroplast consists of stacked vesciles structure. Hence option B is correct

Thus , option B is correct
