mitochondria in ear lobe cells are nearly____________?
Correct answer: B. 50
- A. 40
- B. 50
- C. 55
- D. 60
Explanation
An ear-lobe cell is relatively inactive compared with a muscle cell, so it contains approximately 50 mitochondria in the textbook estimate used here. Students may choose 40 because mitochondrial numbers vary between cells, but the expected rounded value in this question is 50.

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.
