Question

Select the incorrect statement.

• A. The chloroplasts are generally smaller than mitochondria
• B. Both chloroplasts and mitochondria contain an inner and an outer membrane
• C. Both chloroplasts and mitochondria contain DNA
• D. Both chloroplasts and mitochondria can produce most of their proteins

Answer 1

The correct option is A The chloroplasts are generally smaller than mitochondria

Generally, the size of the chloroplast (5 to 10 $\mu$m long) is bigger than that of the mitochondria (0.75-3$\mu$m ). Both chloroplast and mitochondria are double membraned organelles that contain their own DNA and ribosomes. Due to the presence of DNA and ribosomes, they are able to synthesize most of the enzymes required by it.
