My favorite part of the cell is the cell membrane. Why? Because so many interesting things happen on and in the cell membrane.
Just think - what is the first thing that happens when a sperm meets an egg during fertilization? - cell membrane interaction of course. What is involved when a neuron gets excited and fires a nerve impulse? - cell membrane transport changes, that's what happens. When the environment gets freezing cold, what do cells do? - put on "kinky" cell membranes.
I could go on and on about cell membranes but I think you get what I mean. There is so much going on and in cell membranes. I can actually use up one whole class period just talking about cell membranes but this is not a class but a blog. So this is where I stop today. But I hope I got you thinking about cell membranes.
