Question

Animal cells are characterized by the presence of

• A. a true nucleus
• B. endomembrane system
• C. centrosomes and centrioles
• D. all of the above

Answer 1

The correct option is D all of the above

Animals are eukaryotes which have a true nucleus (nuclear membrane, chromosomes and nucleolus) and all membrane bound cell organelles.
The endomembrane system comprises the endoplasmic reticulum, golgi complex, lysosomes and the vacuole.
The centrioles in animal cells help in spindle formation during cell division. Two perpendicularly placed centrioles make up the centrosome.
