Vacuole

• Fluid filled compartment within a cell • Large and permanent in plant cells (filled with

cell sap)• Small or absent in animal cells

Vein

• Type of Blood vessel• Brings blood into the heart• Have valves• Low in oxygen (except the pulmonary vein)

Velocity

• Speed in a given direction ms-1

• Acceleration = Change in velocityTime taken

Valency

• The number of electrons that an atom will give take or share so that it has a full outer shell like the nearest Noble Gas and is stable

•  e.g valency of sodium is one • valency of carbon is four• valency of chlorine is one

Vertebrate

• Animal with a backbone e.g. human or cat

Voltage• Also called potential difference• Voltage forces electrons to move around a

circuit (the push) • V = Current X Resistance• Measured in volts (V)• Measured in parallel• Measured using a voltmeter

Ohm’s law

Volume

• The amount of space an object takes up – its size

• Measured in cm3 or m3

• Volume = LxWxH• Or Use a measuring cylinder • Or overflow can and measuring cylinder

• Do I know it??• Vacuole• Vein• Velocity• Valency
