Select the wrong statement from the following :
1 Both chloroplasts and mitochondria contain an inner and an outer membrane
2 Both chloroplasts and mitochondria have an internal compartment, the thylakoid space bounded by the thylakoid membrane in both
3 Both chloroplasts and mitochondria contain DNA
4 The chloroplasts are generally much larger than mitochondria
Explanation:
In Mitochondria inner compartment is filled with a dense homogeneous substance called the matrix. The inner membrane forms a number of infoldings called the cristae (sing.: crista) towards the matrix In chloroplast membrane of the thylakoids enclose a space called a lumen.
