* Vacuoles: While vacuoles are present in both plant and animal cells, they are much larger and more prominent in plant cells. They play a crucial role in storing water, nutrients, and waste products.

* Cell Walls: Cell walls are a rigid outer layer found exclusively in plant cells. They provide structural support and protection.

* Chlorophyll: Chlorophyll is the green pigment found in chloroplasts that is essential for photosynthesis. It's only found in plant cells.

* Chloroplasts: Chloroplasts are the organelles responsible for photosynthesis in plants. They are not found in animal cells.

Therefore, vacuoles are the only option that is found in both plant and animal cells.
