What exactly is the relationship between the cell size and the movement into and out of the cells.??

I believe that the only relationship would be the difference in surface area of the cells. A larger surface area would allow larger amounts of inflow/outflow. The size of the cell would not affect the size of material that could enter or leave the cell.
My biology is a little rusty, but I think thats it.

The relationship is the 'square-cube law`.
For any given shape, the surface area
varies as the square of the dimension,
the volume as the cube of the dimension.
As cells get larger, the volume of cell that
must be nourished / ventilated by a given
area of the cell wall increases.
Larger cells become unworkable beyond
a certain point.

It's not the size of the cell, but the properties of the surface membranes of the cell. For example, linoleic acid is needed by cells but is too big to pass through the cell membrane. So the body breaks up the molecule, shoves it into the cell, and re-assembles it inside.
Hope this helps?
