Which pair of structures is present in animal cells but absent from plant cells?

1. Both animal and plant cells carry microtubule organizing centers. 2. Only animal cells add centrioles to that center, and the complex is called the centrosome. 3. Animal cells also carry lysosomes, which plant cells lack. 4. Ribosomes, mitochondria, the nucleus and the plasma membrane are shared by both, so those pairs cannot be the answer. 5. Centrosomes and lysosomes are the animal-only pair. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 4 "Cell Structure", section 4.3 Eukaryotic Cells_
