Characteristics of Living Things
ClickBiology
There are 7 characteristics of living organisms:
• Movement• Respiration• Sensitivity• Growth• Reproduction• Excretion• Nutrition
ClickBiology
Movement• A change of position or place.
ClickBiology
Respiration• A chemical process in which oxygen is
used to release energy from sugar molecules.
Sugar (C6H12O6) reacts with oxygen (O2)
to form
Carbon dioxide (CO2), water (H2O) and
ENERGY
ClickBiology
Sensitivity• The ability to detect or sense changes in
the environment (stimuli) and to make responses.
ClickBiology
Growth• A permanent increase in size by
increasing cell number or cell size or both.
ClickBiology
Reproduction• The process that makes more of the same
kind of organism
ClickBiology
Excretion• The removal of toxic materials, waste
products and excess substances from an organism
ClickBiology
Nutrition
The process in which nutrients are taken into the body and converted into simpler substances used for energy, growth and tissue repair.
ClickBiology
Summary
• Movement• Respiration• Sensitivity• Growth• Reproduction• Excretion• Nutrition
