Question

Why are chloroplasts considered semiautonomous organelles?
Options
A They use nuclear DNA only
B They contain their own DNA and ribosomes, allowing partial self-replication
Correct Answer
C They cannot produce any proteins
D They function only under cellular respiration
Correct Answer

Option B is the correct answer.

Detailed Explanation

Like mitochondria, chloroplasts have their own circular DNA and ribosomes and can synthesize some of their own proteins. They grow and divide within the cell but still depend on nuclear genes for many functions.

Hint

They have some, but not complete, genetic independence.
