Diffusion
The movement of molecules from a higher concentration to a lower concentration.
What is diffusion?
Water moves from an area of high concentration to an area of a low concentration during this process.
What is osmosis?
This transport requires no energy.
What is passive transport?
This lab showed how water moves in and out of a candy when placed in different liquids.
What is the gummy bear lab?
The substance that does the dissolving in a solution.
What is the solvent?
This type of diffusion occurs when a substance diffuses though the cell membrane without any help from other molecules
What is simple diffusion?
When a cell is in a hypotonic solution, water moves in and the cell does this.
What is get bigger? (swell)
This transport requires energy to move materials.
What is active transport?
This lab showed how salt pulls water out of vegetables.
What is the Kimchi Lab?
The substance that gets dissolved in a solution.
What is the solute?
This type of diffusion occurs when a substance diffuses through the cell membrane with the help of transport proteins.
What is facilitated diffusion?
When a cell is in a hypertonic solution, water moves out and the cell does this.
What is get smaller? (shrink)
Diffusion moves from a *blank* concentration to a *blank* concentration.
What is higher to lower?
This gummy bear in the gummy bear lab got bigger or swelled.
What is the tap water gummy bear?
A solution with more solutes than inside the cell.
What is a hypertonic solution?
Molecules that pass though the cell membrane by facilitated diffusion include large and this other molecule.
What is hydrophobic molecules?
When a cell is in a isotonic solution, there is no net movement which makes the cell do this.
What is nothing? (cell stays the same)
An active cellular process where membrane-bound vesicles transport large molecules from inside the cell to the external environment.
What is exocytosis?
This gummy bear in the gummy bear lab got smaller or shrank.
What is the salt water gummy bear?
A solution with fewer solutes than inside the cell.
What is a hypotonic solution?
When molecules spread out evenly.
What is equilibrium?
Osmosis helps cells keep this condition where things are balanced.
What is homeostasis?
This molecule provides this energy for active transport.
What is ATP?
This gummy bear in the gummy bear lab stayed the same.
The main reason water moves in or out of the cells.
What is to balance concentration? (reach equilibrium)
