Plasma Membrane
What is the function of the plasma membrane?
What is controls what goes in and out of the cell?
True or False: Passive transport requires energy.
What is false?
Define osmosis.
What is the movement of water across the plasma membrane?
What is when water moves from high conc. to low conc?
What is the diffusion of water?
True or False: Active transport requires energy.
What is true?
What is cellular transport?
What is the movement of molecules in and out of the cell through the plasma membrane?
Name the molecule that is the main component of the plasma membrane and how many layers it is composed of.
What is phospholipid / lipid bilayer?
What is the type of passive transport that involves the diffusion of water?
What is osmosis?
In this type of solution, the same quantity of water molecules go in and out of the cell.
What is an isotonic solution?
Fill in the blanks: Active transport moves particles from a ______ concentration to a ______ concentration.
What is low to high?
What are the 2 main types of cellular transport?
What are active and passive transport?
The vocabulary term which states that a membrane only allows certain particles to pass through it.
What is selectively permeable / semi-permeable?
Where does passive transport occur in the cell?
What is the plasma membrane?
In this type of solution, there is more solvent outside the cell and more solute inside the cell.
What is a hypotonic solution?
Process of releasing substances to the outside of the cell.
What is exocytosis?
What is the main difference between passive and active transport?
What is passive does not use energy, and goes with the concentration gradient?
What is active uses energy, and goes against the concentration gradient?
Name the components that transport molecules across the plasma membrane via facilitated diffusion.
What is channel proteins and carrier proteins?
Fill in the blanks: Passive transport moves particles from a ______ concentration to a ______ concentration.
What is high to low concentration?
This vocabulary word indicates that a cell has lost water and shrivelled.
What is a crenate?
The process of a cell specifically bringing in food particles via surrounding it and pulling it in with the membrane.
What is phagocytosis?
What is simple diffusion?
Name ALL 5 structures that make up the plasma membrane.
What is the phospholipids, cholesterol, carbohydrates, channel proteins and carrier proteins.
List the 3 types of passive transport.
What is simple diffusion, facilitated diffusion, and osmosis?
This is the type of tonicity that plant cells consider normal.
What is hypotonic solution?
Some active transport occurs with the aid of carrier proteins, most commonly called pumps. For example the Sodium-Potassium Pump. Explain how many and in which direction (i.e. into or out of the cell) the pump transports sodium and potassium.
What is transports 3 sodium ions out of the cell while moving 2 potassium ions into the cell?
This is the specific term for a cell using the membrane to engulf water particles.
What is pinocytosis?
