Polysaccharides cross the plasma membrane through diffusion?
Yes, carbohydrates can diffuse through a plasma membrane. Proteins can also pass through the fluid membrane, as well as a few other things.
What depends on a molecule that can cross the plasma membrane?
The Gonhiqule depends on a molecule and cross the plasma membrane in an animal cell, but is a different story for the plant cell because of the cell wall.
What kinda ions are positively charged and can cross back and forth across the neuron cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
What is cell membrane permeability?
It is the ability of the membrane to allow ions and/or particles to cross.
Which molecues cross the membrane of a cell easily and which do not?
Non-polar molecules (such as fatty acids, steroid hormones and O2) pass freely through the cell membrane. Small uncharged molecules (such as H2O) also pass freely, but are slower. Large, polar molecules and ions (such as Na+ and K+) do not pass freely. Macromolecules (such as proteins and polysaccharides) do not pass through the cell membrane. Molecules and ions that cannot pass freely through the cell membrane rely on other means, such as protein transporters, to move in to the cell.

What ions are positively charged and can cross back and forth across neuron and cell membrane?
There are two ions that can cross the cell membrane. The positively charged sodium and potassium ions can cross back and forth across the neuron cell membrane.
Which particles-starch or Lugol's-were able to cross the model cell membrane?
The particles that were able to cross the model cell membrane was the Lugol's solution.

How does CO2 cross the cell membrane?
No, carbon dioxide does not need a transport protein to cross the cell membrane. It can pass through a membrane by diffusion.
What is it when ions are in a low concentration outside a cell and they slowly cross the membrane into the cell?
the answer is the membrane are probably broken down
What receptor has a ligand that can cross the cell membrane that binds?
Intracellular
What is the cell wall of a plant?
The cell wall of a plant cell is the outer layer that maintains cell's shape and protects cell from mechanical damage; made of cellulose , other polysaccharides , and protein.
Can steriods and cholesterol cross the cell membrane on their own?
Yes because the cell membrane allows non polar molecules through
