How does the surface area to volume ratio of a cell affect the rate of diffustion of materials across the cell's surface?
What determines the size and shape of cells in multicellular organisms?

Increased surface area means increase diffusion capability.

The higher the surface are: volume ratio the higher the rate of diffusion. Diffusion is the movment of particles accross a semi permible membrane, and so the more the surface, the more diffusion.
If the volume is large and surface big little diffusion can occur

small cells with large surface area have a higher rate of diffusion cell shape is given by the chromosomes in the nucleus.
In plants the shape of the cell is maintained by the cellulose cell wall and the turgor pressure inside the cell. And the plants are supported by the lignin coating of their xylem vessels.
In animals.. well I don't not. I just know that the whole organism is given a form and is supported by the skeleton.
