What is the difference between plant and mammalian cells?

Plant cells and mammalian cells do share many similarities, but they each have key differences and functions that make them so respectively individual. Both are eukaryotic, therefore similar in structure, but plant cells are larger, sometimes significantly. Mammalian cells are typically round and irregular in shape, while plant cells are fixedly rectangular. A plant cell has a cell wall, while this cannot be found in a mammalian cell. Additionally, chloroplast and vacuoles are only found in plant cell.
