are found only in plant cells, but are found in both plant and animal cells.

As you are comparing plant cells to animal cells, the answer could be a combination of the following:

Cell wall/chloroplasts/plastids/central vacuole are found only in plant cells, but the Golgi body/ mitochondrion/nucleus/cytoplasm/plasma membrane/rough and smooth ER (endoplasmic reticulum)/ribosomes are found in both plant and animal cells.

What the answer is perhaps depends on the context of the question.

I hope you can use this to your benefit!
