Which of the following are similarities between mitochondria and chloroplasts?
A
Both produce glucose as a primary function.
B
Both are involved in photosynthesis.
C
Both have their own DNA and ribosomes.
D
Both are found in animal cells.
Verified step by step guidance1
Begin by identifying the primary functions of mitochondria and chloroplasts. Mitochondria are primarily involved in energy production through cellular respiration, while chloroplasts are involved in photosynthesis.
Understand that both mitochondria and chloroplasts have their own DNA and ribosomes, which is a key similarity. This feature supports the endosymbiotic theory, suggesting that these organelles originated from free-living bacteria.
Recognize that chloroplasts are involved in photosynthesis, whereas mitochondria are not. This distinction helps eliminate options that incorrectly associate both organelles with photosynthesis.
Note that mitochondria are found in both animal and plant cells, while chloroplasts are typically found only in plant cells and some protists. This helps eliminate options that incorrectly state both are found in animal cells.
Conclude that the correct similarity between mitochondria and chloroplasts is that both have their own DNA and ribosomes, which is a unique feature among organelles.
