Carly Geller 11/6/09 Biology Bastos A eukaryote cell can be compared to 1 st Mariner Arena. The cell wall is like the outer structure of 1 st Mariner Arena. The cell wall forms a barrier between the inside of the cell and the outside so that the chemical environments on the two sides can be different. It serves as a strong barrier of protection for plant cells. It keeps the inside of the cell safe from outside harmful things. The arena’s outer structure serves as the strong outer configuration. The outer structure makes sure that what is going on inside the arena is strongly protected. It shields the inside of the arena from bad weather or anything that could be a hazard. The channel proteins are like the turnstiles to enter 1 st Mariner Arena. The channel proteins only allow specific molecules/ions to pass through, thus crossing the membrane. The channels can be ligand-gated, voltage-gated, or mechanically-gated. They facilitate diffusion and active transport. This can be compared to turnstiles
