Question 32

What is endosymbiosis?

Answer 32

Mitochondria and chloroplast were once free-living prokaryotes that now live in eukaryotic cells. "living inside"

Question 33

Evidence for endosymbiosis

Answer 33

Mitochondria and chloroplasts have circular DNA like prokaryotes. Mitochondria and chloroplasts have double membranes. Mitochondria and chloroplasts divide like prokaryotes.
