Question

Which of the following structure or functions is commonly associated with chloroplast, mitochondria, and polysome?

a. Synthesis of carbohydrates and proteins
b. Semi-autonomous organelles
c. Translate mRNA into proteins d. Produce cellular energy in the form of ATP.
d. Membrane-bound organelles

Mark the correct option .

• A. (b) & (e)
• B. (a), (c) & (d)
• C. only (c)
• D. (a), (b),(c) & (d)

Answer 1

Answer: (C)

only (c)

Mitochondria and chloroplasts are semi autonomous cell organelles since they possess their own DNA and ribosomes. In animal cells, mitochondria have their own DNA and ribosomes.Although mitochondria and chloroplasts are membrane bound organelles, ribosomes are membraneless organelles. Ribosomes also do not produce ATP like mitochondria and chloroplasts and they do not produce carbohydrates. Thus, the only common feature among these organelles is that they translate mRNA into proteins.

So the correct option is 'only (c)'.
