Cell Membrane and Diffusion Review

This regulates the movement of molecules from one side of the membrane to the other.

• cell membrane

• equilibrium

• passive transport

• diffusion

What is the movement of molecules from an area of high to low concentration and does not require energy?

• osmosis
• diffusion
• facilitated diffusion
• active transport

What are the two other names that you can use for the cell membrane?

• plasma membrane, fluid mosaic model
• plasma membrane, outer layer
• plasma membrane, cell membrane
• plasma membrane, cytoplasm

Transport of a substance without the use of energy.

• PassiveTransport

• Active Transport

• Pinocytosis

• Phagocytosis

What does semipermeable membrane mean?

• A membrane that will allow certain molecules or ions to pass through it.

• The membrane of a plant cell that only lets water through.

• A membrane that allows only carbon molecules to pass through the membrane.

• A membrane that does not allow anything into or out of the cell.

What does phospholipid bilayer mean?

• A two-layered row of specialized proteins.

• A Chloroplast layer that protects the cell nucleus.

• A two-layered arrangement of phosphate and lipid molecules that form a cell membrane, the hydrophobic lipid ends facing inward and the hydrophilic phosphate ends facing outward.

• It is the layers that cover the surface of the cell and allows water to pass into the cell membrane.

What is diffusion?

• The mitochondria moving water across the cell membrane but never into the cell.

• The process of enzymes catalyzing the reaction in the nucleus.

• The movement of only water inside the cell.

• The movement of particles from a region of higher concentration to regions of lower concentration.

what does passive transport mean?

• It is the movement of only water molecules across the membrane using energy.

• It is the displacement of enzymes across the cell membrane.

• It is the movement of only carbon ions into the cell membrane through enzymatic displacement.

• It is the movement of ions and other atomic or molecular substances across cell membranes without need of energy input.

What does concentration gradient mean?

• The process of the nucleus sending messages to the Golgi apparatus.

• The process of particles moving through a solution from an area with a higher number of particles to an area with a lower number of particles.The areas are typically separated by a membrane.

• The process of the mitochondria pumping solution out of and into the cell through cell membrane pores.

• The process of particles moving through a solution from an area with a lower number of particles to an area with a higher number of particles.The areas are typically separated by a membrane.

What part of the cell membrane is the arrow pointing to? 

• phospholipid
• carbohydrate chain 
• protein channel 
• amino acid
