Question

How might the cells of the membrane pore compare to the size of the starch molecules?

Answer 1

the pores are too tiny for the starch to move through it, the glucose does pass through it if the glucose is not complex, it must be simple glucose

Answer 2

Membrane pores are part of cells. And these pores are to small for big starch molecules to pass through, but perhaps the simpler glucose molecule could pass through.
Hope this helps!
