Given the list you have offered here, cell wall is the
best choice, but the wording of the question is critical. Cell walls are never found in
animal cells, but are not exclusive to plants, as fungi have them too, albeit made of a
different material. Additionally, the term "part" is a bit sticky here - plant cells
secrete the cell wall and live within it, but it's not really part of the cell, and it's
not an organelle at all, a misunderstanding I have encountered many
times.
Chloroplasts are not limited to plants, they are
found in a number of groups of protists as well. However it would be good to bear in
mind that not all plants have chloroplasts; there are some species of parasitic and/or
saprophytic plants that do not (Monotropa uniflora, or Indian
pipes, comes immediately to mind as an example). Additionally, chloroplasts are a
subgroup of the plastids; one type of plastid that is indeed limited to plants is
amyloplasts.
Virtually every cell, plant or animal, has one
or more vacuoles, the major distinction between plant and animal cells on this score is
what percent of the cell's net volume is taken up by
them.
Regarding the converse of this question, plant cells
never have lysosomes or centrioles, and animal cells do.
