Endosymbiosis theory states that mitochondria and chloroplasts were once
prokaryotes that were endocytosed by a larger cell, and came to live in symbiosis
with that larger cell rather than being digested in a lysosome. Choose ALL the lines
of evidence for this theory from the list below.

Mitochondria and chloroplasts are enclosed by a double membrane, which would
have happened if they had been endocytosed.

12
Mitochondria and chloroplasts have their own DNA, separate from the DNA in
the nucleus, and that DNA is arranged in a single circular chromosome, just like
prokaryotic DNA.

Mitochondria and chloroplasts can be removed from the cell and live
independently of it.

H
Mitochondria and chloroplasts have their own ribosomes to build their own
proteins, and the ribosomes are small prokaryotic ribosomes rather than the
larger eukaryotic ribosomes.
24
Mitochondria and chloroplasts divide independently of the rest of the cell.
