Question Detail
Question
Which is found only in animal cells: a. nucleus b. mitochondrion c. centriole d. plasmid
Correct Answer
Option C is the correct answer.
Detailed Explanation
Centrioles are cylindrical organelles involved in organizing the microtubules during cell division (forming the spindle apparatus). They are found in animal cells and most protists, but are generally absent in higher plant cells. Nuclei and mitochondria are present in both. Plasmids are small DNA circles in bacteria.
Hint
This structure helps animal cells divide and is typically not found in plant cells.
