The statement that does not serve as proof that mitochondria and chloroplasts evolved from bacteria is: **b) they have chromosomes similar in shape to their host.**
While mitochondria and chloroplasts do have their own circular DNA that is similar to bacterial DNA, their chromosomes do not resemble those of the host cell, which are typically linear and found in the nucleus. The other options (a, c, and d) provide evidence supporting the endosymbiotic theory.
