Amoeba is a eukaryotic unicellular organism.
MCQ
Assertion (A): Eukaryotic cells contain membrane-bound organelles. Reason (R): Compartmentalization of functions increases efficiency in eukaryotic cells.
  • A. Both A and R are true, and R is the correct explanation of A
  • B. Both A and R are true, but R is not the correct explanation of A
  • C. A is true, R is false
  • D. A is false, R is true
βœ… Correct Answer: A
Eukaryotic cells contain membrane-bound organelles such as nucleus, mitochondria, ER, and Golgi bodies. These allow separation of metabolic processes, thereby increasing efficiency.
