Parts that both have in common include: cell membrane, nucleus, nucleolus, ribosomes, golgi apparatus, cytoplasm, peroxisomes, vacuoles, endoplasmic reticulum. However, there are organelles particular to plant cells. The cell wall which is non-living and protects the plant cell and provides a structural framework on the outside of the cell is one organelle found in plants, not animals. Also, the chloroplasts which contain the pigment chlorophyll which allows plant cells to absorb sunlight and carry out photosynthesis are unique to plant cells. The vacuoles in plant cells are very large and can store materials such as water. Animal cells have an organelle called the centriole which aids it during mitotic cell division. Plant cells do not have the centriole. The vacuoles are much smaller in animal cells. If you memorize the parts unique to either plant or animal cells and remember that all the other parts can be found in both, it may simplify things.
