Document Summary
They metabolize energy and transfer it as atp. The cell is the basic unit of life. The cells that extend from the spinal cord to the muscles (down to the toe) of an animal like a giraffe is over a meter long. (in all mammals) All cells are made of the same type of molecule and the membranes of all cells are made of the same lipids. And the proteins and the dna are composed of the same chemistry. The longer the distance, the longer the diffusion takes. As distance increases, it takes longer for substances to diffuse. So cell has to be small enough to keep up with the diffusion of oxygen to support their demand. 2- as surface area increases, the volume stays the same. 3- the larger the cell gets, the more substrates it needs. By making an organism made of a lot of small cells rather than one big cell, you eliminate the surface area:volume problem.
