Animal and plant cells have many similarities, but they also have some key differences. Here's what they don't have in common:

* Cell Wall: Plant cells have a rigid cell wall made of cellulose that provides structural support and protection. Animal cells lack this cell wall.

* Chloroplasts: Plant cells contain chloroplasts, which are organelles responsible for photosynthesis. Animal cells do not have chloroplasts.

* Vacuoles: Plant cells have a large central vacuole that helps maintain turgor pressure and stores water and nutrients. Animal cells may have smaller vacuoles.

* Centrioles: Animal cells have centrioles, which are involved in cell division. Plant cells typically lack centrioles.
