What structures are found in plant cells that are not found in animal cells?
solong [7]

There are three major structures that are found in plant cells that aren't found in animal cells. These are chloroplasts, (which is where the process photosynthesis takes place), a cell wall (which keeps the structure of the cell), and a large central vacuole,  (which stores extra food/water). Don't make the mistake, though.  Animal cells have vacuoles, but they are just smaller and not as important, because they have a different way of excreting waste, which plant cells cannot do.
