Question

Which of the following can be cited as evidence for the theory of endosymbiosis?

Mitochondria are typically above 50 microns in size, whereas eukaryotic cells are typically smaller than 10 microns.

Mitochondria contain multiple linear chromosomes similar to those found in eukaryotic cells.

Eukaryotic cells appeared on Earth around 1.5 billion years ago, whereas chloroplasts appeared on Earth only 2.5 million years ago.

The 70S ribosomes of chloroplasts are more similar to the 70S ribosomes found in prokaryotes than the 80S ribosomes found in eukaryotes.
