THE CELL PROBLEM WHY WE ARE MADE OUT OF CELLS

(0)
The cell is the individual unit of life. It evolved over long ages and is pretty good. It has many fantastic tricks. It can even reproduce by splitting in two! However, there is a problem. Cells work better if small. This is because if small, oxygen and other substances can come in and out easier being right near the cell boarder. Cells evolve toward higher function. Some have tails to swim, mouth like parts, eye spots. But..they must contend with the basic fact.. cells work better if small. So how can bigger, higher functioning animals be made? The solution is to have an animal made of cells working together. This has many advantages: Cells can specialize. New animals can be made with a rearraigement of cells following similar plans. Cells can die and be replaced without much disruption to the whole animal. So, we are to made of a union of cells. We must understand ourselves as a collection of cells which have mostly given up their independance for a better existance in a place created by their collective efforts!
