====[|The Cell Membrane]is perfect for all your micro needs! With a strong skin, both plant and animal cells are effectively protected. Certain molecules are allowed in, and the membrane even holds it's important parts (such as the nucleus) inside! Other foreign objects, like sugar and amino acids, are studied closely by the cell membrane to keep their amounts in check. Waste is even let out of this fantastic product, through the permeable layer. Protein is built and some is included into the bilayer. Lipids in the bilayer, known as phospholipids (a water-loving part) feature a phosphate (a water-fearing part) group on each molecule's tail, for free! This amazing product's phospholipids face the outside, and the phosphates face the inside. Buy this amazing holder for the very low price of $59.99.====
