An animal cell is different from plant cell because the cell wall and chloroplasts are absent in animal cell. The cell wall is important part of cell because it protect the cell for its sustenance in plants kingdom. But in animal kingdom the cell is enclose in plasma membrane and do not have a cell wall. Hence, as compared to the eukaryotic cells of plants and fungi, animal cells do not have a cell wall and chloroplasts.
