[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
All of the following are evidence of endosymbiosis EXCEPT
|
|
mitochondria and chloroplast ribosomes are similar to bacterial ribosomes
|
|
|
mitochondria and chloroplast are similar in size to bacteria
|
|
|
mitochondria and chloroplast have double membranes
|
|
|
mitochondria and chloroplast have a nucleus
|
Explanation:
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: -In addition to the lack of histones, mitochondria and chloroplasts have circular, single stranded DNA. Single stranded, circular DNA is found exclusively in prokaryotes. This evidence supports the endosymbiosis theory because these characteristics would allow the mitochondria and chloroplasts to survive on their own.
Detailed explanation-3: -The chromosome similarity of organelles (mitochondria and chloroplast) does not support the endosymbiotic theory and having non-coding DNA.
