Active transport
Active/Passive transport
100
The random movement of molecules from an area of higher concentration to one of lower concentration.
What is simple diffusion?
100
When a sac, bag, or membrane of any kind will allow only certain molecules through it.
What is semi - permeable?
100
What happens to a cell when it is placed in a hypertonic solution.
What is shrinkage/shriveling?
100
Getting rid of substances in the cell
What is exocytosis?
100
Carrier proteins that "use energy"
What is active transport?
200
This type of diffusion or passive transport requires a carrier protein.
What is Facilitated diffusion?
200
The diffusion of WATER across the cell membrane.
What is Osmosis?
200
The phrase used to describe the direction of osmosis (water) from a place of greater concentration to one of lower concentration.
What is "down the concentration gradient"?
200
When using the analogy of a hill, this is the direction you are going during active transport.
What is uphill.
200
"Cell drinking"
What is Pinocytosis?
300
One molecule that we said needed Facilitated diffusion to help get it through the cell membrane.
What is glucose?
300
The major part of the cell membrane.
What are Phospholipids?
300
When using the analogy of a hill, this is the direction you are going during passive transport.
What is downhill?
300
A sodium "pump".
What is an example of active transport?
300
The direction of ions during "active transport".
What is "against the gradient" or Low to High concentration?
400
When molecules don't really move in one direction more than the other across the membrane. This situation occurs when everything is "ok".
What is Dynamic Equalibrium?
400
The condition that a fresh water plant cell would be in if placed in salt water.
What is plasmolysis?
400
Diffusion across the membrane WITHOUT the use of energy.
What is Passive transport?
400
The energy to move substances "against the gradient"
What is ATP?
400

Phagocytosis

What is active transport?

500
The part of the Phospholipid bilayer that is "water hating".
What are the hydrophobic tails?
500
The solution that causes the cell to take in water.
What is a HYPOTONIC solution?
500
When cell transport keeps the cell healthy and normal.
What is HOMEOSTASIS?
500
"Taking in" substances through active transport.
What is "Endocytosis"?
500
When there is a higher concentration of solute inside a cell.
What is a hypotonic solution?
