What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What is a semipermeable mebrane?
The cell membrane is called as semi-permeable membrane because it allows only certain/selective molecules to pass through it.It mostly allows only solvent molecules to pass.It is sometimes also called as selectively permeable membrane.
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
What part of the cell is referred to as to fluid mosaic model?
The cell membrane or plasma membrane is often referred to as the fluid mosaic model. This is because it is composed of a fluid lipid bilayer with embedded proteins, giving it a mosaic-like appearance. The fluidity allows for the movement and exchange of molecules within the membrane.
Substances that can pass through cell membranes by diffusion include?
depends on type of membrane 1) semi-permeable membrane - allows only solvent molecule to pass ex. parchment paper 2) permeable membrane - allows both solvent and solute molecules to pass ex. filter paper 3) selectively permeable membrane - allows solvent molecules and some of selected solute molecules to pass ex. plasma membrane
What properties does a selective permeable membrane have?
the ability to allow materials to cross a membrane
What is membrane permeability?
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.
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
What is meant by membrane is membrane?
a partially permeable membrane allows some molecules or ions to pass through it
What part of the cell membrane allows small molecules to pass through?
the cell membrane
What is selectively permeable?
The property of a membrane or other material that allows some substances to pass through it more easily than others.Selective permeability refers to the control that a cell membrane has in terms of what it allows to cross it. This gives the cell membrane the ability to choose which molecules enter or leave.

What do you call a cell membrane that allows certain molecules to pass through?
A selectively permeable membrane.
What phrase best describes osmosis A process by which A the cytoplasm divides B DNA synthesizes C molecules distribute balanced by movement D selectively permeable membrane allows exchange through it?
Osmosis is the process where a selectively permeable membrane allows the movement of water through it.
