Flashcards in Osmosis Deck (11):
What is osmosis?
Osmosis is the diffusion of water from a high to low concentration
If there is a low solute level but a high water level the water diffuses
What is diffusion?
Diffusion is the spreading out / movement of particles from a high concentration to a low concentration
Which out of Diffusion, Osmosis and Active Transport requires carrier proteins?
Active Transports requires carrier proteins because it moves from a low to high concentration
What is Active Transport?
Active transport is diffusion from a low concentration to a high concentration
It needs carrier proteins and energy to move up / against the concentration gradient
What scientific word do we use to describe a *swollen* red blood cell?
We call a *swollen* red blood cell TURGID
A red blood cell becomes turgid when water is diffused into it via osmosis (because of a low concentration of water inside the RBC)
What scientific word do we use to describe the process of a Red Blood Cell *shrinking*?
We use the word CRENATION to describe the process of a Red Blood Cell *shrinking*
Cremation is the process of Shrinking
This occurs when there is a high concentration of water in the RBC and it diffuses out
What is likely to occur when a Red Blood Cell swells and becomes Turgid? (Beginning with an H)
Haemolysis can occur when a RBC swells and becomes Turgid.
Haemolysis is the splitting of a RBC
Haemolysis = Human
What is likely to occur when a Plant Cell shrivels and Crenates when it loses water? (Beginning with an P)
Plasmolysis is likely to occur when a Plant Cell Shrivels and Crenates when it loses water
It is when the protoplast of a plant call contracts as a result of loss of water
What is a solvent?
What is a solute?
A solvent is the liquid in which x dissolves
A solute is x(which dissolves)
What are the concentration levels in a *Hypotonic* solution?
There is a low concentration of solutes and a high concentration of water in a *Hypotonic* solution
Low concentration of solutes = High concentration of water
