Get animal cell facts, including a labeled cell diagram , a list of organelles and their functions, and a summary of animal cell types. The plasma membrane Like bacteria and archaea, eukaryotic cells have a plasma membrane, a phospholipid bilayer with embedded proteins that separates the internal contents of the cell from its surrounding environment. The plasma membrane controls the passage of organic molecules, ions, water, and oxygen into and out of the cell . Wastes (such as carbon dioxide and ammonia) also leave the cell by passing through the plasma membrane, usually with some help of protein transporters. Figure 2. The ... The diagram of eukaryotic cell showcases its various cell organelles such as the nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, vacuoles, lysosomes and the plasma membrane. The difference between prokaryotic and eukaryotic cells can be easily understood with the help of a diagram of eukaryotic cell class 9. Learn about the eukaryotic cell .
