The diagrams show the shape and size of two types of cell.
Which statement is correct about the palisade cell and epithelial cell shown in the diagrams?

1 )
An increase in surface area reduces the distance for gases to reach the centre of the cell.
2 )
The surface area of the palisade mesophyll cell is $500\mu {m^2}$ greater than the columnar epithelial cell.
The surface area to volume ratio is greater in the columnar epithelial cell than the palisade mesophyll cell.
4 )
The volume of the palisade mesophyll cell is $2500\mu {m^3}$ greater than that of the columnar epithelial cell.
