Plant cells have a cell wall, a large central vacuole, chloroplasts, and other specialized plastids, whereas animal cells do not.
Animal cells have a centrosome and lysosomes while plant cells do not.
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.
Another category of interactions between organisms has to do with close, usually long-term interaction between different types of organisms. These interactions are called symbiosis
