Diffusion Basics
This process involves particles (liquids and gasses) moving from an area of higher to lower concentration.
What is diffusion ?
Osmosis involves the movement of this molecule/particle.
What is water ?
This organelle is the gatekeeper of the cell.
What is a cell membrane?
Tea particles spreading into the water.
What is diffusion?
A cell is placed into a salt solution, water flows this way.
What is water moving out of the cell?
Diffusion continues until everything is spread out.
What is evenly ?
Water is flowing in this direction.
What is an area of lower concentration (higher solute)?
The cell membrane chooses what comes in and out of the cell.
What is selectively permeable?
The celery experiment is an example of this process.
What is osmosis?
School have a "no scent policy" because of this process.
What is diffusion ?
These three types of particles are allowed to cross into a cell.
What is oxygen, water, nutrients ?
These particles are suspended in the solvent.
What is a solute?
The cell membrane presses against plant cell walls.
What is turgor pressure?
This method of slip prevention on the roads relies on a solute.
What is salt ?
In order for osmosis to occur you need a difference in this.
What is a difference in concentration?
Tea particles spreading out of the tea bag.
What is diffusion ?
A plant cell has lost too much water.
What is a decrease in turgor pressure?
Keeping solute concentrations in ____ is a key function of the cell membrane
What is balance ?
This is the process that kidney's use to maintain water balance in the body.
What is osmosis?
The lungs allow oxygen and carbon dioxide to pass through the cell walls using this process.
What is diffusion?
Diffusion is a form of this type of transport.
What is passive transport ?
A plant cell has taken in water.
What is turgid?
Lower solute concentration leads to this process.
What is osmosis?
Placing a carrot into water to make it rigid.
What is osmosis ?
A vacuole filling up with water represents this process.
What is turgor pressure?
