Which statements about chlorop*yujcxgf *y11lasts and mitochondria support the endosymbi ujit:lzs5,ewp ,1ye8 otic theo u5tp,e1s8w,:ijey zl ry?
A. Chloroplasts is Contain 70S ribosomes;Mitochondria is Contain cristae
B. Chloroplasts is Found in prokaryotes;Mitochondria is Contain 80S ribosomes
C. Chloroplasts is Have a single membrane;Mitochondria is Contain circular DNA
D. Chloroplasts is Contain 70S ribosomes;Mitochondria is Have a double membrane
参考答案: D
本题详细解析:
The endosymbiotic theuqbeffv*)k:b/ : sl2 rory states that larger prokaryotes engulfed smaller prokaryotes, which were the ancestors of modern chloroplasts and mitochondria. The smaller prokaryotes were engulfed via endocytosis, so they have their original membrane as well as the membrane of the larger prokaryote. Both chloroplasts and mitochondria have 70S ribosomes and a double membrane. Choice D is correct.Choice A is incorrect because the fact that mitochondria contain cristae is not due to the endosymbiotic theory. Choice B is incorrect because chloroplasts arekue) /*bfs : r:bqflv2 not found in prokaryotes. Choice C is incorrect because chloroplasts have a double membrane.
