Which pair of structures is found in animal cells but generally not in plant cells?

1. The comparison runs both ways: plants have structures animals lack, and the reverse. 2. Animal cells each have a centrosome and lysosomes, whereas most plant cells do not. 3. Ribosomes and nuclei are in both, so that pair separates nothing. 4. Cell walls, chloroplasts and large vacuoles run the other way, being plant features. 5. So the animal-only pair is centrosomes and lysosomes. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 4 'Cell Structure', sections 4.1-4.6_
