Organelles are_______________?
Correct answer: C. Sub-cellular structures
- A. Unicellular structures
- B. Multi-cellular structures
- C. Sub-cellular structures
- D. Non-cellular structures
Explanation
Organelles are specialized sub-cellular structures within a cell, such as mitochondria, ribosomes, and endoplasmic reticulum. They perform particular functions but are not complete cells or multicellular structures. The likely alternative is non-cellular structures, due to misunderstanding that organelles are separate from the cell, although they are parts of cells.

About Cytoplasmic Organelles
Cytoplasmic organelles are the specialized structures suspended in cytoplasm, including mitochondria, ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles and centrosomes. Questions compare their structures and functions in animal and plant cells, including chloroplasts and the role of the endomembrane system in transport and secretion.
