permeability
Yes, charged molecules can pass through the membrane.
Ions cannot pass through the cell membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through. Ions have an electric charge that makes it difficult for them to pass through the hydrophobic interior of the membrane.
Yes, hydrophobic molecules can pass through a membrane because the lipid bilayer of the membrane is also hydrophobic, allowing them to move through easily.
No, large polar molecules cannot pass through the plasma membrane.
Large molecules such as proteins and nucleic acids cannot pass through the cell membrane.

permeability
the separation of disolved molecules based on their ability to pass through a semipermeable membrane.
Waste can pass through a membrane due to its size and composition. Membranes have small pores or channels that allow smaller molecules or ions to pass through, while larger molecules or particles are blocked. Additionally, the chemical properties of the waste may also play a role in its ability to pass through a membrane.
Yes, charged molecules can pass through the membrane.
Membrane permeability refers to the ability of molecules, substances, etc. to pass through the membrane. For example, the cell membrane is referred to as 'semi-permeable' because it allows some molecules (such as water) to enter, and stops other molecules (such as sodium ions) from passing through the membrane. If these want to get into the cell, they must then rely on proteins in the cell membrane to let them in.
The cytoplasm of a cell is surrounded by a cell membrane or plasma membrane. The membrane is said to be 'semi-permeable', in that it can either let a substance pass through freely, pass through to a limited extent or not pass through at all.the membrane is somewhat effective at letting fluids through
Ions cannot pass through the cell membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through. Ions have an electric charge that makes it difficult for them to pass through the hydrophobic interior of the membrane.
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
Yes, hydrophobic molecules can pass through a membrane because the lipid bilayer of the membrane is also hydrophobic, allowing them to move through easily.
Permeable if anything can go through or semipermeable if only certain things can go through it.
