Question

multiple - choice question
what is the first evidence that supports the endosymbiotic theory?
chloroplasts and mitochondria do not divide on their own like prokaryotes. they are produced by the cell.
chloroplasts and mitochondria divide on their own like prokaryotes. they are not produced by the cell.

Explanation:

The endosymbiotic theory suggests that chloroplasts and mitochondria were once free - living prokaryotes. One of the key pieces of evidence is that they divide on their own (similar to prokaryotes) and are not produced by the cell in the same way as other organelles. The first option is incorrect as it states the opposite of what supports the theory.

Answer:

Chloroplasts and mitochondria divide on their own like prokaryotes. They are not produced by the cell.
