Mitochondria, Endoplasmic Reticulum, Golgi apparatus, Cytoskeleton, Plasma membrane and Ribosomes are found in both plant and animal cells. Vacuoles can both be present in animal cells and plant cells. However, they are much smaller in animal cells and can be more than one, whereas a plant cell usually only has one big vacuole. Lysosomes and Flagella are usually not found in Plant cells.
