|
|
Mitochondria and chloroplasts have DNA that is similar to that found in the nucleus
|
|
|
Mitochondria and chloroplasts are able to replicate their own DNA
|
|
|
Mitochondria and chloroplasts develop at the same time
|
|
|
Mitochondria and chloroplasts replicate in a way similar to some prokaryotic cells
|
Detailed explanation-1: -"The exterior structure similar to bacterial cell walls” IS NOT an evidence in favour of the endosymbiotic theory. Both mitochondria and chloroplasts are double membrane bound.
Detailed explanation-2: -The chromosome similarity of organelles (mitochondria and chloroplast) does not support the endosymbiotic theory and having non-coding DNA.
Detailed explanation-3: -So, the correct answer is’The mitochondria and chloroplast have their own DNA’
Detailed explanation-4: -Evidence for Endosymbiosis Evidence that supports the extracellular origins of these organelles can be seen by looking at certain key features: Membranes (double membrane bound) Antibiotics (susceptibility) Division (mode of replication)
Detailed explanation-5: -Abundant evidence has been found for endosymbiosis: Mitochondria and chloroplasts divide by binary fission (a form of asexual reproduction), just as bacteria do, and not by mitosis as Eukaryotes do. Mitochondria arise from preexisting mitochondria; chloroplasts arise from preexisting chloroplasts.
