What is the difference between a semi-permeable and a partially permeable membrane?
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:
What is a membrane that allows some substances to pass through but excludes others?
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.
Using an example explain what is meant by a partially permeable membrane?
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.
Is glucose permeable or impermeable?
Glucose is permeable, meaning it can pass through cell membranes.
Is the Visking tubing a partailly permeable membrane and why?
Yes, it is a partially permeable membrane. It allows certain substances like glucose and water molecules to diffuse through but not large molecules like starch and sucrose. Selectively permeable.
What is meant by partially permeable?
a partially permeable membrane allows some molecules or ions to pass through it
What type of molecules allow only certain molecules to pass through it?
semi permeable membranes
What membranes are there in osmosis?
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.

Cell membranes that allow certain molecules to pass through while keeping others out are called?
semi permiable I believe, but I'm not 100 percent sure on the spelling selectively permeable
What is meant by membrane is membrane?
a partially permeable membrane allows some molecules or ions to pass through it
What does osmosis do?
The random movement of water molecules through a partially permeable membrane from a higher concentration to a lower concentration.

Why are don't starch molecule pass through partially permeable molecule?
Starch molecules are large polysaccharides composed of numerous glucose units, making them too big to pass through the pores of a partially permeable membrane. These membranes allow the passage of smaller molecules like water and certain solutes but act as barriers to larger macromolecules. As a result, starch remains confined to one side of the membrane, while smaller molecules can move freely. This selective permeability is crucial for maintaining cellular homeostasis.
Cells have selectively what membranes?
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.
what does semi-permeable mean?
It means it has a cell wall.
