Cell+Membrane+G7

This here is the cell membrane! Inportant for any cell collector! Its the wall that holds the cell together! But, it does much more than that!

The cell wall is made of these, jellyfish like structures, called lipids, which are fats. The "heads" are hydrophilic, which means they draw towards water, while the "tails" are hydrophobic, meaning that they draw away from water. These lipids create a solid barrier, that prevent viruses, and any unwanted material from getting through, very handy, to avoiding detting sick! Unless your the kind of person, who wants to get sick, to avoid that school test, or job coming up! Ha, ha! This cell membrane does not suffocate the cell by keeping everything out of it, oh no! This cell is selectively permeable, meaning it lets some important things through, like water, or protiens. A very prime thing to add to any cell lovers collection! I'd say it runs at about $40.00? Wadday ya say?
