Summary
Highlights
Animal cells are typically round and irregular in shape, while plant cells tend to be fixed in a rectangular or cube shape. Animal cells can also have cilia or flagella and contain centrioles that aid in cell division, structures generally absent in plant cells.
Both plant (PC) and animal (AC) cells are eukaryotic, meaning they possess a nucleus that houses their genetic material, protecting it from damage like a 'lock box'. The nucleus also functions as the 'brain of the cell', controlling its activity and providing instructions for protein synthesis. They also share other membrane-bound organelles such as mitochondria, endoplasmic reticulum, and the Golgi apparatus. The plasma membrane is also a shared feature, acting like skin to protect both cell types.
Plant cells have chloroplasts, an organelle where photosynthesis takes place. This process allows plants to convert sunlight, water, and carbon dioxide into sugar (glucose) and oxygen. Animal cells lack chloroplasts and must obtain sugar for energy through consumption.
Plant cells possess a cell wall, a strong supporting layer around the cell membrane, which is absent in animal cells. The cell wall, made of cellulose, provides structural support, maintains cell shape, and protects against pathogens.
Plant cells have a much larger central vacuole compared to animal cells. This large vacuole stores substantial amounts of water, food, and other substances, which is crucial since plants cannot actively seek out water like animals.
