Osmosis

Question 1

What is osmosis?

Answer 1

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

Question 2

What is diffusion?

Answer 2

Diffusion is the spreading out / movement of particles from a high concentration to a low concentration

Question 3

Which out of Diffusion, Osmosis and Active Transport requires carrier proteins?

Answer 3

Active Transports requires carrier proteins because it moves from a low to high concentration

Question 4

What is Active Transport?

Answer 4

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

Question 5

What scientific word do we use to describe a swollen red blood cell?

Answer 5

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)

Question 6

What scientific word do we use to describe the process of a Red Blood Cell shrinking?

Answer 6

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

Question 7

What is likely to occur when a Red Blood Cell swells and becomes Turgid? (Beginning with an H)

Answer 7

Haemolysis can occur when a RBC swells and becomes Turgid.

Haemolysis is the splitting of a RBC

Haemolysis = Human
H=H

Question 8

What is likely to occur when a Plant Cell shrivels and Crenates when it loses water? (Beginning with an P)

Answer 8

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

Question 9

What is a solvent?

What is a solute?

Answer 9

A solvent is the liquid in which x dissolves

A solute is x(which dissolves)

Question 10

What are the concentration levels in a Hypotonic solution?

Answer 10

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

Question 11

What are the concentration levels in a Hypertonic solution?

Answer 11

There is a high concentration of solutes and a low concentration of water in a Hypertonic solution

High concentration of solutes = Low concentration of water
