The endosymbiotic theory provides compelling evidence that mitochondria and chloroplasts were once primitive bacterial cells. how are chloroplasts and mitochondria similar to prokaryotes? all but one apply.
a) chloroplasts and mitochondria contain dna
b) chloroplasts and mitochondria have a nucleus
c) chloroplasts and mitochondria contain ribosomes
d) chloroplasts and mitochondria have a double membrane

B) Chloroplasts and mitochondria have a nucleus

Explanation:

Mitochondria and chloroplasts, like bacteria have:

* membranes

* ribosomes

* DNA

B) Chlorplasts and mitochondria have a Nucleus

Explanation: This are from Usatestprep

Chloroplasts and mitochondria have a nucleus. is not correct. While mitochondria, chloroplasts, and prokaryotes all contain DNA, none of them have a nucleus.

Mitochondria and chloroplasts, like bacteria have:

* membranes

* ribosomes

* DNA

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
