Question 11

A leaf cell of a bean plant contains both mitochondria and chloroplasts. Which statement correctly describes a structural similarity or difference between these two organelles?

Both organelles possess a double membrane and circular DNA, but only mitochondria contain 70S70\text{S}70S ribosomes.

Cristae are found in mitochondria but not in chloroplasts, whereas thylakoids are found in chloroplasts but not in mitochondria.

Both organelles contain stroma, but only chloroplasts have a highly folded inner membrane to increase surface area.

Mitochondria have 70S70\text{S}70S ribosomes and circular DNA, whereas chloroplasts contain 80S80\text{S}80S ribosomes and linear DNA.
