2.11 Origins of Compartmentalization

Why do mitochondria and chloroplasts have DNA in them?

• They were once prokaryotic cells.

• They produce their own DNA through photosynthesis.

• They receive the DNA from the nucleus.

• They process the DNA of the cell.

Tags

All of the following are evidence of endosymbiosis EXCEPT

• mitochondria and chloroplast ribosomes are similar to bacterial ribosomes

• mitochondria and chloroplast have double membranes

• mitochondria and chloroplast are similar in size to bacteria

2.10 Compartmentalization

Which of the following best summarizes an advantage for eukaryotic cells in having internal membranes?

• Eukaryotic cells are able to reproduce faster because of the presence of organelles.

• Some organelles, such as mitochondria and chloroplasts, are similar to prokaryotic cells in structure.

• Internal membranes allow cells to separate specific reactions, increasing their efficiency.

• Compartmentalization leads to a higher mutation rate in DNA, which leads to more new species.
