"Osmosis" and "Active Transport"

A Revision quiz on Osmosis and Actuve Transport, think you know your stuff?- Put it to the test!

?
What is Osmosis?
The movement of water molecules only, across a partially permeable membrane.
1 of 11
What is Diffusion?
The spreading out of the particles of a gas, or of any substance in a solution.
2 of 11
The larger the difference in concentration...
the quicker the rate of difussion
3 of 11
Particles always move via diffusion from...
an area of high concentration to an area of low concentration
4 of 11
During osmosis...
Water molecules move from an area of high WATER concentration to an area of lower WATER concentration.
5 of 11
Active transport is used to..
absorb substances across a partially permeable membrane against the concentration gradient.
6 of 11
When do cells need to use active transport?
To absorbs specific substances such as ions or sugar from dilute solutions.
7 of 11
True or false?- A root cell absorbs mineral ions from the dilute solutions in the soil by active transport?
True
8 of 11
True of False?- Glucose can be reabsorbed in the kidney tubules by active transport?
True
9 of 11
