The cell use something called a protein channel that helps larger particles across the cell membrane.
The molecule will be transported across the membrane by way of a transport protein or protein channel.
A large cell will never move across an intact cell membrane.
Water is the molecule that will move easily across the cell membrane. It can cross the membrane through special channels called aquaporins. Large proteins, starch, and DNA are too large to pass through the membrane without assistance.
Its too large
it separates from the membrane.

A large cell will never move across an intact cell membrane.
It requires energy, and a protein carrier molecule. The large particle binds to the protein carrier on the inside of the cell. It is then transported across the membrane as a result of a conformational change in the protein (think of it flipping), and then it is released on the outside of the cell. Again, this requires some source of energy.
Small particle accelerators can sit on a desktop, large circular ones can be miles across

Small particles move faster across the membrane.
