The liquid that transport substances in the body
What is blood
A solution with more water than solute
What is a dilute solution
The spreading out of particles from where are many to where there are few
What is diffusion
The build-up of electric charges
What is static electricity?
Tiny particles of matter
What is atoms
A gas transported by red blood cells to body cells
What is oxygen
Water moving from the soil into a plant
What is an example of osmosis
This gas diffuses out of the blood into the lungs to be breathed out.
What is carbon dioxide
A charged pen will attract small pieces of this material.
What is paper?
Anthing that have mass and occupies space
What is matter
These are transported from the small intestines to the body cells for energy.
What is nutrients?
The part of a cell that allows some things to pass into the cell
What is a cell membrane
Unlike osmosis diffusion can happen in liquid, gases and these....
What are solids
Static electricity is caused the movement of these tiny particles.
What are electrons?
The positive particles of an atom
What is proton
The part of blood that transports dissolved substances such as glucose, and hormones.
What is plasma?
A membrane that only allows somethings through it
What semipermeable/ selectively permeable
Diffusion happens more slowly when the temperature is this
What is low/ cold
A natural event that is caused by a large build-up of static electricity in clouds.
What is lightning?
The subatomic particles of an atom
What is proton, electrons and nucleus
Gas transported by the lungs and used by the body for respiration
What is oxygen
The difference in concentration of two substances on either side of a barrier
What is a concentration gradient
This coloured substance spread through water during diffusion
What is ink/ food colouring/ dye/ potassium crystals /purple crystals
Rubbing two objects together creates static electricity through this process.
What is friction?
The number of positively charged protons is equal to the number of negatively charged electrons
What is an electrically neutral atom
