Albumin and starch molecules are too big to diffuse across cell membranes. They will not be able to diffuse from the intestine into the blood and from blood into the cells.
An impermeable membrane is that through which no substance can pass. Semipermeable membranes are those that let only solvents, like water, to pass through it. Permeable membranes are those that let solvent and solutes, like ions and molecules, to pass across it. There are also selectively permeable membranes, i.e., membranes that besides allowing the passage of solvent, let only some specific solutes to pass while blocking others. See link:
A membrane that lets some substances pass through but not others is known as a semipermeable membrane. Other terms that describe this type of membrane are: selectively permeable, partially permeable, or differentially permeable.
A partially permeable membrane is a barrier that allows only certain substances to pass through while blocking others based on their size or properties. For example, a cell membrane is partially permeable because it allows water and small molecules to pass through while blocking larger molecules like proteins.
Glucose is permeable, meaning it can pass through cell membranes.
In Biology, a selective permeable cell means the cell only allows certain molecules to pass through. This concept was first introduced to understand the process of osmosis, where solute molecules move along a concentration gradient through a semi permeable membrane (also known as a selectively permeable membrane) Cells allow water molecules and small ions to pass through their membranes without the expenditure of energy.

semi permeable membranes
Semipermeable membranes are used in osmosis. Semipermeable membranes let some molecules pass through them but not others, so they are partially or semi permeable. For example, the membrane may let smaller size molecules pass though but block larger molecules sort of like a sifter. Thus the two molecular substances can be separated.

semi permiable I believe, but I'm not 100 percent sure on the spelling selectively permeable
a partially permeable membrane allows some molecules or ions to pass through it
The random movement of water molecules through a partially permeable membrane from a higher concentration to a lower concentration.
Cells have selectively permeable membranes that allow certain substances to pass through while blocking others. This selectivity helps maintain the internal environment of the cell by controlling the movement of molecules in and out.

For example, a cell membrane is partially permeable because it allows water and small molecules to pass through while blocking larger molecules like proteins.
Glucose is permeable, meaning it can pass through cell membranes.
It means it has a cell wall.
