Before starch can enter a cell, it must be
(1) absorbed by simple sugars
(2) diffused into simple sugars
(3) digested to form simple sugars
(4) actively transported by simple sugars

Starch are macromolecules that are made of monomers that are simple sugars. Cells are microscopic and they can only absorb small substances. Therefore starch needs to be digested in other words broken down into simpler substances that can be taken in by cells. Therefore before starch can enter a cell it must be 3) digested to form simple sugars
